The trigonometric functions Analysis index History Topics Index The use of trigonometric functions arises from the early connection between mathematics and astronomy. Early work with spherical triangles was as important as plane triangles. The first work on trigonometric functions related to chords of a circle. Given a circle of fixed radius, 60 units were often used in early calculations, then ...

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 ...
