A unit circle has a center at (0, 0) and radius 1. In a unit circle, the length of the intercepted arc is equal to the radian measure of the central angle t. Let (x, y) be the endpoint on the unit circle of an arc of arc lengths. The (x, y) coordinates of this point can be described as functions of the angle.
