Trigonometry and Music
Sounds are produced by things that vibrate. Pure tones, like the the sounds produced by tuning forks, are described by sine waves y = A sin(2 pi f t), where t is time, f is how many times the thing is vibrating per second (f is for frequency , and A is how loud the sound is (A is for amplitude). If something is vibrating 256 times a second, you hear middle c. Sound of middle c (.wav file) Here is the graph. You can see that there are about, well, 25.6 waves during one tenth of a second. If we show you one second in the same amount of space, it just looks like a blob. If we double the frequency of any tone, we go up exactly one octave. So 512 vibrations per second is c above middle c. C above middle c (.wav file) Here is the graph. We get more complex sounds by adding waves of different frequencies and loudnesses together. A violin string or an oboe cavity will vibrate with more than one frequency at once, usually at multiples of a fundamental frequency. Here is a wave with components at 512 Hertz, 1024 Hz, 1536 Hz and 2048 Hz (1 Hz = 1 vibration per second). Sound of this wave The higher components are called harmonics of the fundamental tone. If the fundamental is c at 512 Hertz, then the second harmonic is twice the frequency, c an octave higher at 1024 Hertz, the third harmonic is g at 1536 Hertz, and the fourth harmonic is c at 2048 Hertz. A musical tone consists of the fundamental and many harmonics added together.

The applet Triangle and Law of Sines emphasizes that the mathematical symbols denoting lengths, angles and trigonometric functions in a triangle stand for concrete numbers. Furthermore, it illustrates (two versions of) the Law of Sines. Note that the applet does not provide a proof of the latter. For a multimedia proof see The Law of Sines by Math Education and Technology.
The applet is started from the red button in its own window.

High quality mathematics problems for middle school and high school math competitions. Topics range from algebra and geometry to probability and trigonometry. Pricing is available upon request.

Math Competition Problem Writer
Quality Mathematics Problems For High School and Middle School Competitions
One of the great ways to inspire students to learn more about mathematics is to hold competitions in which students compete against students from their own school, or from around the state, or country. Problem solving skills are sharpened, while teamwork is encouraged. The end result is that students think more critically, understand concepts better, and learn to work well together.
Douglas Twitchell, who maintains Virtu Software's Problem Of the Week page, experienced this first hand throughout his elementary, secondary, and college career. Twitchell is a former competitor and award winner in a variety of state and national math competitions. He has won awards and recognition in leagues such as MAML, NEML, ASMA, NEAML, and in college he ranked in the top 150 in the prestigious William Lowell Putnam exam.
In recent years, he has been hired by various mathematics leagues, such as the Maine Association of Math Leagues, the Maine Algebra and Geometry League, and others, to write creative and challenging math problems for middle school and high school mathematics competitions.
Whether it's a regional, state, or school competition, consider hiring Doug to write problems for your math meet. The problems are carefully crafted and written, with diagrams where appropriate, all cleanly formatted for printing. Each problem is proofed to guarrantee both accuracy and clarity. Proofing is done by a high school math teacher and math team coach, and the proofing cost is included.

Let's see how far you can get with just those I've done so far and a few simple laws (so you can add and subtract and multiply and divide angles). Please note that getting 1/3 of an angle is equivalent to trisecting it, a classic impossible problem! ( Advanced - because the answer depends on solving a cubic. The answer is rather dirty-looking, anyway). back to top And there are as many more as you care to memorize (always a mistake!). The hard part will be in coming up with smaller divisions (such as 5 degrees) without the arithmetic getting infinitely hairy. The author tried for hours and gave up! back to top II. Trig
