WEBSince C = 2πr, the circumference of a unit circle is 2π. In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.

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 $(x \;-\; a)^2 + (y \;-\; b)^2 = r^2$ becomes
