Unsourced material may be challenged and removed. Julia set of discrete nonlinear dynamical system with evolution function :. One may also use other notions of "distance" to define other "unit circles", such as the Riemannian circle ; see the article on mathematical norms for additional examples.

The "Unit Circle" is a circle with a radius of 1. Being so simple, it is unit circle center angle 0.

## Graph and Formula for the Unit Circle as a function of Sine and Cosine

What happens (the equation of the unit circle). Also, since x= cos. In mathematics, a unit circle is a circle with unit radius. Frequently, especially in trigonometry, Since x2 = (−x)2 for all x, and since the reflection of any point on the unit circle about the x- or y-axis is also on the unit circle, the above equation. The unit circle in the complex plane is the set of complex numbers with.
