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. In topology, it is often denoted as S because it is a one-dimensional unit n-sphere. If (x, y) is a point on the unit circle's circumference, then x and y are the lengths of the legs of a right … WebOct 23, 2024 · A unit circle has a radius (r) of 1, which gives it a circumference of 2𝛑, since circumference = 2𝛑r.
