The Unit Circle Written by tutor ShuJen W. The above drawing is the graph of the Unit Circle on the X â 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: (1, 0), (0, 1), (-1, 0), and (0, -1) This is important to remember when we define the X and Y Coordinates around the Unit Circle. The Unit Circle has 360Â°.
