1-0 out of 5 stars I did not like it at all!
I felt my instructor is not doing too well when it comes to teaching and I didn't want to buy the expensive textbook for the class. So I bought this book in hopes I could learn something. I learn by being shown solutions to a problem, but this book doesn't give you that. It only gives you the 411 on the subject which I still don't understand... This book is a mess! Out of desperation, I ended up buying an expensive crappy used-book from a_teambooks sellers here in Amazon.

4-0 out of 5 stars from complex to simple
Trig for Dummies helps me understand the basics, and advanced concepts, in trigonometry. If you're thinking about buying this book, I suggest it. I had no regrets after I purchased it.

This a very good learning tool for someone who doesn't know a thing about trigonometery. I am glad to find such a product that is like having a tutor around 24 hours a day. Thank you, Lyle J. Christenson.

2-0 out of 5 stars Are you kidding??
18 pages in, and I find an egregious error:

Page 18:
Example: Find the area of a circle if the angle between the two radii forming the sector is 80 degrees and the diameter of the circle is 4.5 inches.

1. Find the area of the circle.
The area of the whole circle is A=(pi)r² = (pi) · (4.5)² = 3.14 · 20.25 = 63.585, or about 63½ square inches.

Now, either this is poor math (by not converting the diameter into radius), or poor editing (by meaning radius as opposed to diameter).Whichever it is, it doesn't instill a lot of confidence in the book.

5-0 out of 5 stars Excellent reference book
bought the books for my daughter who is an elgebra teacher, who wants to
go on.She is enjoying the books very much and is on the sixth chapter of the trig. book and workbook.She is also working the pre-calculus book and workbook. So far as a mom I'm batting a hundred.Thank you.

4-0 out of 5 stars Trigonometry Workbook for Dummies
I purchased this workbook for my grandson to augment the material he is using in school. It has helped him immeasureably in understanding trigonometry and going a bit farther than the classroom curriculum goes. He has shown increased interest in the subject as a result.

3-0 out of 5 stars Too Many Errors; Proofreading is Missing
I was in a bit of a quandary as to how to rate this book.I bought the book and the companion "Trigonometry for Dummies" to refresh my trig skills, long rusted after nearly 50 years of little use.Both books are really quite good although the workbook could be more comprehensive.The big problem with this workbook, and to a lesser extent with the "Trigonometry for Dummies" book, is the large number of errors and typos in the book.One works out a very complicated identity problem only to find that the stated problem is different from the problem answered due to typographical errors.I don't think I went seven pages without finding an error.Most of the errors were changed minus or plus signs.This made maintaining confidence in the book very difficult.

One would think that a big publisher like Wiley would employ competent proofreaders.I would also expect them to have an errata sheet somewhere on their web page.But, nooo, nothing helpful there at all except a glossary they forgot to put in the main trig book.

Overall, both books were very helpful, with the exception of not having a lot of confidence that the answer to the problem I was trying to solve would be correct.

4-0 out of 5 stars a first course in trig
If you have never done trigonometry before, Sterling gives a gentle introduction. She assumes some previous acquaintance with geometry and simple algebra and analytic geometry. But not too much of the latter, so don't let this scare you off.

The trig concepts are slowly introduced and explained at some length. With plenty of examples. Now, you really should tackle as many of the problems as possible. Yes, it takes time. But if you want a solid, fluid grasp of trig, you have to spend the time to familiarise yourself with sine, cosine, tangent, cotangent, secant and cosecant.

There are certainly numerous relationships between these functions. You don't have to know all of them. But being acquainted with them, and knowing where to look for formulae in a book like this is useful. ... Read more

This book arrived very fast, in only 3 days. Although there were some pencil marks inside, it was in good condition.

5-0 out of 5 stars Great book-no need for a teacher!
I used this textbook last year for my Algebra II class. I personally loved this book. It had very good, worked-examples in each section that were exactly the same as the practice problems given. Most textbooks start out with some information explaining what is going on, and then the student is just supposed to put the pieces together on how to do the problems, whereas the examples in this book show the student exactly how to do the problems. My algebra teacher was not very good, and while she did work out examples on the board for the class, they just never made sense. By the end of the year, I stopped even listening to her lessons and I just did the problems in the book on my own. I made an A in the class, and even though math is one of my weaker subjects, I think I learned enuogh to do fine on the SAT and ACT.

However, my teacher disliked this book. She said that it really needed to include more graphing, and that it was outdated.

To each his own, I guess. I definitely think that its many clearly layed out examples helped me.

1-0 out of 5 stars from a college math instructor
This book is improperly organized - concepts in mathematics must be understood from the easiest level to the most difficult - this book presents the material for memorization, NOT understanding. This is the first time that I encounter math organized in such a way. While everything is explained well enough, the lumping together of too much information for difficult concepts makes it difficult to learn properly. Try McKeague instead, same title, just a much better book.

4-0 out of 5 stars Thorough
Many say Schaum's is "just an outline", a "supplement to the textbook".Well, first of all, there are few trig textbooks out there; mostly one learns trig in a few chapters during pre-cal high school class. And I doubt most high school students (including me) really understood or remember "the theory".I just bought this book, and am now on the vectors chapter.I feel I understand every section just fine.Some of the problems are written in a confusing manner, however. For example, one problem talks about "evenly-spaced holes in a circle". I tried doing the problem by putting dots onto a circle, but the problem meant "holes" as "points" on the circumference of a circle. Another problem talked about a lighthouse seeing a boat heading "due south", and then"due west", forcing the student to intuit this as a 3-D trig problem. I didn't, and solved a 2-D problem instead.In the vectors chapter, it also makes a couple of assumptions. One is that the windspeed angle must form a 90 degree angle from the airspeed vector, in order for you to solve it. The example diagram clearly shows an obtuse angle, but the problem shows what appears to be a 90 degree angle. Of course, in order to even solve it, it MUST be 90 degrees. But Schaum's did not say this angle MUST be 90 degrees. Unless you are sharp, you'll miss the fact that you cannot solve EVERY airspeed/groundspeed/windspeed vector problem!On the example of the inclined plane and the weight, Schaum's simply states that the angle between the Weight vector and the F vector is the SAME as the angle of inclination.I had to sketch out the triangles on a piece of paper and realize this is true BECAUSE the triangles are similar, because they share a similar side and 90 degrees of an angle.So Schaum's is NOT for the lazy!But I'm not lazy. I work hard at solving problems and understanding math, and Schaum's has taught me a lot in their College Algebra text about inequality proofs, theory of equations, and solving determinants with minors--stuff that is NOT really covered that well in anything else BUT a textbook. But textbooks suck, right? With all their tons of pages, sidebars/distractions, pictures,and lack of distillation, you will be spending way too much time trying to understand some minor point, while you still have 30 more pages to go to finish the chapter. The result with textbooks is that you don't really know where you stand on the subject. With Schaum's, I feel confident after going through each chapter and working hard, that I WILL grasp and understand not only the fundamentals of the topic, but almost every aspect about the topic that is mentioned in textbooks.

4-0 out of 5 stars Schaum's Trigonomertry, 4th Ed.
Actualym, the book was intended as a gift. If it were for me I would have to given itmuch lower rating -- since I am from the old school and the symbology had some logic behind it this make little sense unless I took the time to converty all that I know then start from scratch.. It appears that all of the newer math books are copies of others work with just differenmt symbology -- more to confuse and not to standardise. Seems the Hypotenuse, adjacent, and opposite are no longer in vogue. The new make things up as they go along, then with its Mediocrity , it becomes a standard. Too bad, we have to continually be confused. No sense, no logic, no worry how it affects out fellow man.

But, since the person had no previous background, they did not notice any differences -- so they thought they would find good use for it.

As usual Schaum is a pretty good reference and representative book.

3-0 out of 5 stars Non-comprehensive
A little background on my situation. I need to pass (preferably with an "A")college trigonometry in order to obtain my degree. Math has always been my weak area. I had attempted to take it about a year and a half ago, and it didn't end well. I ended up dropping the class.
Since then, I have decided to barge into the mathematics world once again in order to properly defeat trigonometry. My plan was to get a comprehensive book on trig and learn everything during the summer; then, I won't feel so behind and lost in class. I choose this book due to the great reviews.
I'm on page 50. It's not what I expected at all. It goes into great detail on the easy topics and hardly does anything on the difficult ones. It doesn't show all the steps to solving the math. It doesn't explain how to use your calculator along with the equations (i.e. When do you press cos, sin, tan, cot, etc. in the equations?).
This book reminds me of borrowing notes from someone that is doing really well in class.It doesn't really teach you what's going on, but if you know what's going on, it could come in handy. I think perhaps when I am getting assignments, and I want to better understand it, this book will be useful. However, it's not capable of TEACHING. It's more like a handy reminder for people who already know. The description for it, I feel, was inaccurate. I think I'm going to invest in Dummies. Sigh.

5-0 out of 5 stars Great Book !
Received the book in quick order which is usually the case from Amazon and was impressed with the first look at the book.Have not had a great amount of time to get into it yet but the first impression on leafing through the pages is that it appears to be laid out well and am looking forward to it.

5-0 out of 5 stars Excellent trig book
I bought this book and Trignometry for Dummies to help me prepare for my first trig exam in college.My professor is good, but his explanations aren't always clear and I really needed something to bridge the gap.This book does an excellent job of explaining not only HOW to do things, but WHY.It's even better than the textbook I was required to buy for the class.As for the other book, Trig for Dummies, it's just doesn't hold a candle to this one.

5-0 out of 5 stars Outstanding Trigonometry Presentation!
This is the best book out there on learning trigonometry. I especially appreciate the visually oriented focus. Each concept is described in all its forms, such as sine.Do you know each of the different ways sine can be described? Like the other Master Math books by Ross, the topics flow logically and are in context with what precedes and follows.It is thorough yet concise, and packed full of everything you, as tutor, or your kids need to know.The real world and fun applications are wonderful!The information is explained clearly and in a way that makes sense, so that a given concept is explained in such a way you understand what is being discussed rather than just memorizing formulas. What a breath of fresh air after the often-confusing text books I was and my children are given in school. I really feel I understand trigonometry after reading this book! If I were going back to school, and taking math or science, this book would be in my backpack.Also recommend: Master Math: Geometry. Master Math: Algebra. Master Math: Basic Math and Pre-Algebra. Also loved her novel: ARROWS THROUGH TIME: A Time Travel Tale of Adventure, Courage, and Faith

5-0 out of 5 stars For those who've had the math before, but want to brush up

***** 5 stars for content (the authors seem to be very in touch with what explanations work for students both in the short term, and what explanations are best for them in the long term.)

***** 5 stars for the exercises.There are a lot of exercises in each section (usually around 100?).They cover the basics all the way up to what they call the 'sythesis' problems, where the student can challenge themselves to do advanced problems.I really like the synthesis problems because they are do-able and can make the student start to feel confident.

The material presented in this book is straight forward and includes much history of the concepts within Trigonometry. It gives a good holistic understanding of trigonometry, connecting some material to future applications in calculus, though probably not near as much as a trig/calc book of course. The homework problems develop at a good pace. This is not a phenomenal book, but it is definitely a solid text book that will teach you trigonometry well.

This is the best math book ever.The explanations are so clearly laid out that it is almost impossible to not understand it.I wish every math or science book was written the way this one is.The writers have not over complicated the instructions and the examples in the book actually help you with the problems that are at the end of each section.The web site is also very helpful, but I only had to use it for one chapter... because the book was so awesome.This book definitely helped me get an A in the class and helped prepare me for Calculus.

2-0 out of 5 stars Not awful, but frustrating...
This is the textbook for my college trigonometry class. I find it to be rather frustrating, as often, there are section review questions that are NOT covered by the examples, and often require different skills or formulas than you have learned in that section. I have had to google explanations several times when the book's explanation of a concept was inadequate. ... Read more

2-0 out of 5 stars Do not buy this book if you are just beginning Trigonometry.
This book is good for one thing, a Quick Review.I suppose I can't blame CliffsNotes, since that is given in the title of the book.I bought this book when I was beginning to learn Trigonometry, along with another textbook.I found that a lot of the things the textbook went over was not even mentioned in this Quick Review book.If you have taken Trigonometry in the past and want to refresh some of the basic trigonometry concepts, then this book is for you.However, if you know nothing about Trigonometry and want to learn about it, this book will do nothing but CONFUSE you.

Most people that will look into these books are people who want to learn the subject for their first time, so take my advice: instead of buying this book, save that money towards a better, complete basic trigonometry textbook.

1-0 out of 5 stars Take another look
This book seems to be pretty nice, until you start finding all the super horrible mistakes that are thrown in ever couple of pages. They are all do the this book not being edited, and make it a hassle to read as you have to second guess everything that is written. I got about half way done and the mistakes turned me off so bad I put the book away and don't intend to read from it again. This book could have been a real nice book but the mistakes are just too horrible to look over.

5-0 out of 5 stars Handy Little Summary
After several years in a corporate engineering job, I started moonlighting as a math tutor. The Cliff's Quick Review Guides are wonderful to have in my "back pocket" when I need to quickly look something up that is covered in dust in the "archives of my brain."

5-0 out of 5 stars Great series...Great book.
I'm a (returning :P) university Freshman preparing for the College Board CLEP tests.I was already familiar with the material covered in this book, but needed to refresh my memory.This review turned out to be *exactly* what I needed.

The author's ability to explain the material to the student are just shy of enlightening.The discussions & theorem proofs are written in a very concise, clear style.

I'm a big advocate of the Cliff's QuickReview series.Intended as a course supplement, these books are also *GREAT* for students wanting to refine their skills.Most of them are also very accessible to students with less familiarity on the subject; trying to learn it for the first time.

After reading this, I bought the Calculus & Differential Equations QuickReviews & I'm looking forward to reading them! ... Read more

5-0 out of 5 stars Great for Test Review
I first purchased this book over 3 decades ago.I've used it several times, always the night before some sort of aptitude test or exam that included pre-calculus math.I used it to pass the math CLEP test, placement exams for college and grad school, and the ASVAB test to get into the Navy.Each time, I went through the entire book in one evening just before taking the test.It worked like magic.I totally aced the math every time!

5-0 out of 5 stars Outstanding book.
As a professor who teaches Capital Markets in a Masters program in Finance, I only wish that all my students came prepared with this much math (let alone, basic calculus).

To answer criticisms first.This is not a book to learn pre-calculus math from, with no previous exposure -- the explanations are too condensed; the reader is expected to fill-in key steps from his/her previous knowledge.

However, for those reviewing topics for which they already have some understanding, I cannot think of a better book.It cuts down to the essence what often takes 500, verbose pages.It is a excellent summary that requires the reader to be active and think through the steps along the way.

Again, for those who have previously studied the topic, what would be a good follow-on for elementary calculus?Probably, either Spivak:


or Kleppner and Ramsey:


Personally, I would slightly prefer Kleppner and Ramsey (because it goes a little further, without sacrificing understanding).

5-0 out of 5 stars Best quick review I've seen
As a scientist (but not mathematician) I think that this book is an excellent review for students that have already taken these courses in high school in preparation for a college calculus class. It is a distillation of the key principles covered in high school that are necessary to succeed in calculus courses. It could also serve as a preview of upcoming material for motivated students (e.g. a high school student could read the chapter on algebra over the summer before actually taking algebra). It isn't suitable as a stand-alone text, but then it doesn't imply that it is one. I used it in conjunction with a couple calculus review texts ("for Dummies") to refresh after a twenty-year hiatus before successfully tackling differential equations.

5-0 out of 5 stars all good stuff, no fluff
I love this book and refer back to it regularly.It has the most succinct explanations of many subjects in algebra, geometry, and trigonometry that I've seen.What a waste of paper all those other precalculus books are!

2-0 out of 5 stars Inadequate
This book might be used as a quick reference to check formulas, but it's inadequate for learning or even refreshing.Perhaps it's unrealistic to expect much of a book with "in a nutshell" in the title.However, the author doesn't even bother to provide answers to all of the review exercises.Instead, only answers to "selected" problems are shown.There are quite a few superior books available which do a much better job of presenting this material. ...

Buying this book saved me over half of the new purchase price ($165.00) at my college bookstore. This book was in excellent condition for being used. Anyone taking college courses that requires textbooks should look at [...] Bigwords guided me through which books were available and what condition I wanted and if I wanted to rent my books or buy them outright.I recommend bigwords. Dont rent - buy your books outright and resell them at the end of each semester! Purchase decent quality books from sellers who have good recent feedback. Amazon.com is one of the places that [...] automatically found for me. This purchased helped me save a few more dollars and at a time like now, every dollar saved counts.

5-0 out of 5 stars trying to save my son's back
I bought this book to use as a "home copy" for my son's algebra II class.It is a hefty textbook and his school chooses not to buy a class room set.He already has his backpack stuffed to the gills, so for a small sum I lightened his load.

4-0 out of 5 stars School Book
I bought this book as a backup for the one we use in school.The book itself is good with explaining most concepts, but not always clear.Overall, I would suggest this book.

4-0 out of 5 stars Very good, but slightly flawed
I have recently completed a fourteen-week self-study of this entire book, in preparation for an Engineering major.

I found the book very helpful; determinates, f of x terminology, and quadratic functions were explained in an easy to understand manner. Another thing I found helpful was the inclusion of "real world" problems that could be solved using the teachings in this book. Problems in business, biology, nuclear fission, rocket trajectory, etc. are presented and can be solved by the student. Such questions seem to be designed to introduce medical/engineering hopefuls to what they'll encounter in the years ahead.

Furthermore, the trigonometry section is only three chapters long, which I think is very wise of the author; as most 700-page trigonometry tomes are usually overwhelming to students and contain nonsense about determining the heights of flagpoles, which a future doctor or physicist does not need to know by heart!
A determined student can master the essential trigonometric functions in under a month, and this book can serve that purpose.

My only complaints are that some topics are explained in vague ways; I found myself writing my own expositions in the margins. Also, only the odd-numbered questions (1, 3, 5, etc.) are answered in the answer section. This provides less incentive to complete all the questions posed, because mistakes that are made on even-numbered questions will go unnoticed unless the student is extremely thorough in checking.

Despite these drawbacks, I recommend careful study of this book to those students who wish to enter the sciences...but make sure you have someone you can consult with because here and there the book may confuse you.

4-0 out of 5 stars Hmmm, quite a good book with only minimal faults
I found this algebra/trig. book to be very satisfactory, with only a few things I'd change about it.The word problems found in the last section of each chapter offer the right level of difficulty, interesting situations, and the character's names are often quite funny (ex. Butch Err's feedlot, Ripov's Insurance Co., Sue Flay and Cassa Roll's hamburger stand, etc).For many of the problems that involve graphing, the answer at the back simply says (graph).It would be a lot more helpful if the graph was provided, especially if the back of the book is the only means to check homework.This gets a little frustrating sometimes. ...

5-0 out of 5 stars Just-In-Time Algebra and Trigonometry
Great value. Very good condition. Super fast delivery. Would buy from this vendor again. Thank you.

5-0 out of 5 stars Solid if you need a refresher, unsuited if you need to learn it
If you have previously studied and largely understood algebra and trigonometry and just need a quick review, then this book is right for you. However, if you haven't studied these topics or didn't understand them the first time, then it will be of little value. The coverage is thorough in breadth, starting with the basics of adding and subtracting all types of numbers through logarithms, exponential functions and trigonometry. Only a few pages are devoted to each topic with exercises at the end of each section. Solutions to some of the exercises are given at the end, although in my opinion there should have been more.
While the explanations are short, to the extent that it is possible in a small number of pages, they are through in depth. In a section that I found interesting, the dy/dx notation for a derivative is used. However, knowledge of calculus is not required, the reader is simply being asked to algebraically solve for dy/dx rather than use any knowledge of what it represents. Used in the manner for which it was intended this book is an effective tool in the study of precalculus material.
Note: This book is nearly identical to the companion book, "Just-In-Time: Algebra & Trigonometry for Early Transcendental Calculus." It would be a waste of money to buy both.

5-0 out of 5 stars Wow ... great book!!
This book is totally great. I've seen very few books that explain mathematical concepts as well as this. The authors actually made math look easy by providing a lot of examples and writing in a more conversational, informal style (like the style in the Idiot's Guides series). It's a lot clearer than Barron's and Cliffs. Often there is a lot of humor added in.

As the title of this book indicates, this book is intended for calculus students in college who are struggling in their courses. However, for high school students who are using this book to teach themselves new concepts or using this as a tutorial, review, etc. I would recommend this as a supplement to another text. The book is somewhat brief and does not go through the advanced and nitty-gritry areas of algebra and trigonometry. This is intended to be a remedial "catch-up" book and is not targeted specifically towards the hig school student. But high school students, teachers, and curious readers will all find this book very helpful for making hard math look simple.

I'd taken Calculus ten years ago and needed to retake it. After working through 'Forgotten Algebra', this book was a godsend. It's B.S.-free and highly focused on what you need BEFORECalculus. If you buy the first edition used (as I did), then it's cheap.

1-0 out of 5 stars Frustrating and Incomplete
This text was required for my university Trig class. Other reviewers have argued that math text books are only supplemental to the material covered in class - that it's the teacher that makes the difference.If that's the case, without a good teacher, this book is nearly useless. Whether the authors are covering fundamentals or advanced concepts/calculations, most everything gets a very cursory, succinct treatment. Should you not understand something covered in class, this text likely will not help to clarify. If you are at all unfamiliar with Trigonometry (as I was going in to this class), this text is not intended to enhance your understanding. ... Read more

Product Description
"Trigonometry", a work in the collection of the "Gelfand School Outreach Program", is the result of the successful collaboration between two experienced pre-college teachers, one of whom, I.M. Gelfand, is considered the most distinguished living mathematician. Gelfand's impact on generations of young people, some now mathematicians of renown, continues to be remarkable.

All basic topics in Trigonometry are covered with an emphasis on beautiful illustrations and examples that treat elementary trigonometry as an outgrowth of geometry, but stimulate the reader to think of all of mathematics as a unified subject. The definitions of the trigonometric functions are geometrically motivated. Geometric relationships are rewritten in trigonometric form and extended. The text then makes a transition to a study of the algebraic and analytic properties of trigonometric functions, in a way that provides a solid foundation for more advanced mathematical discussions.

Like other I.M. Gel'fand treasures in the program, Algebra, Functions and Graphs, and The Method of Coordinates, Trigonometry is written in an engaging style, and approaches the material in a unique fashion that will motivate students and teachers alike. ... Read more

1-0 out of 5 stars Not very good for self study.
I had purchased this book based on all of the positive reviews from this website and others. However, I was not at all happy with the result. The book itself does not explain anything. It makes learning a chore and kills every ounce of motivation to learn math. My two recently purchased Calculus books (Calculus Made Easy and A First Course in Calculus) made the subject fun and motivating. Everything was explained thoroughly and the solutions were given unlike this Trigonometry book.

Simply put - no solutions, no explanations, and no motivation to learn. It is not a good book for anyone wishing to self learn Trigonometry.

Good luck with your purchases!

4-0 out of 5 stars Good geometrical approach to trigonometry
This book is a very nice change away from the overly analytical approach that most trigonometry texts take nowadays. In my view something is lost when the geometric aspects are not emphasized. There is some fantastic geometry in this book, and I especially liked the connection between the sine addition formula and Ptolemy's theorem for quadrilaterals inscribed in a circle. Those kinds of connections are not only neat in themselves, but I think they help to understand the material better. I think they can spark students' interest more than the dull plug-in-the-numbers types of exercises in most books.

Speaking of the exercises, many of them are excellent. As some other reviewers have mentioned, it's nice to see a book at this level not insult the intelligence of its readers. I wish more elementary math textbooks were like this.

The only criticism I have is that there are lots of errors and typos in the book, enough to make me give it only 4 stars instead of 5. For instance, in Exercise 8 on p.147 it asks the reader to prove that (cos a)^2 <= cos(2a). Of course, that inequality should be reversed. And there are many more annoying little errors like that, which makes me believe that no one actually proofread the book.

2-0 out of 5 stars Huge Disappointment!!
I usually buy books that have good feedback because it has served me well in the past, but unfortunately this isn't the case with this book. The author couldn't have picked a more perplexing way to explain this subject. Yes it's filled with problems, but what good are the problems if you don't have the correct answer nor do you have an explanation on how to solve them. Don't let the wonderful reviews fool you. If you still think it's worth a try, then I advise for you to look at a copy before buying.

4-0 out of 5 stars Trig-Gelfand
This is a very good Trig book. However, there was no offer of an answer book. I will teach a course using this book. Can you give me a site where I can get an answer book? With the answer book I could give 5 stars.

5-0 out of 5 stars Trigonometry is all about triangles!
So I bought this book for some Trig class I signed up for at the last minute. I didn't know what to expect. I skimmed through the book and saw triangles everywhere. I figured that a few triangles should not be so difficult to figure out- the measurements and all. It's a skimpy little book, but there sure is a lot of info crammed in there. I studied hard. I had dreams of triangles floating around, suspended in the air. I could not get triangles off my brain. Day and night- triangles and more triangles. I think I just got sick of looking at triangles come final exam, because I went out and got hammered to get them off my mind just hours before the exam. I'm not BSing you either. To make a long story short, I took the exam while under the influence of alcohol. It worked, the booze got the triangles off my brain, but the timing was not good because I had to think about triangles in order to finish the darn exam. I had a perfect GPA until that Trig exam. I did manage to pull off an A- on the exam, which surprised the heck outta me. Now I try to not let triangles get the best of me anymore. I'm angry at them, but at the same time I understand them.
