Description: A unit circle is a circle of unit radius, i.e., of radius 1. The unit circle plays a significant role in a number of different areas of mathematics. For example, the functions of trigonometry are most simply defined using the unit circle. As shown in the figure above, a point P on the terminal side of an angle theta in angle standard position measured along an arc of the unit circle has as its coordinates (costheta,sintheta) so that costheta is the horizontal coordinate of P and sintheta...
