WebThe Unit Circle Written by tutor ShuJen W. The above drawing is the graph of the Unit Circle on the X – Y Coordinate Axis. It can be seen from the graph, that the Unit Circle is defined as having a Radius ( r ) = 1. Going from Quadrant I to Quadrant IV, counter clockwise, the Coordinate points on the axis of the Unit Circle are: 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 …
