WebEquation of a Unit Circle. The general equation of a circle is of the form ( x − a) 2 + ( y − b) 2 = r 2, where the center of the circle is (a, b) and the radius is r. A unit circle in the x-y plane is formed with a center at origin (0,0) and radius 1. Thus, the equation of the unit circle on an x-y plane is x 2 + y 2 = 1. WebSin 0 Degrees Using Unit Circle. To find the value of sin 0 degrees using the unit circle: Draw the radius of the unit circle, r to form a 0° angle with the positive x-axis.
