Apart from displaying graphs of plotted equations, one of the major innovations of the graphing calculator was the ability to compute the sine, cosine and tangent trigonometric functions.

A sine wave is a geometric waveform that oscillates periodically and is defined by the function y = sin x.

With static graphs and equations, it's possible to get a handle on the rules of what various functions do and mean.
