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. Main article: Circle group. Please help improve this article by adding citations to reliable sources. The unit circle is often denoted S 1 ; the generalization to higher dimensions is the unit sphere. If necessary, round the answer to two decimal places.

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