Downloadable simulation of how the sine and cosine functions are made from rotation through a circle. Get a feel for how trig functions relate to coordinates and lengths. Imagine a point that starts at and rotates counterclockwise on the unit circle. If is the length (in radians) of the arc on the circle between and the point, then as the point moves around the circle its and coordinates are the cosine and sine of .
