The Unit Circle is a circle where each point is 1 unit away from the origin (0,0). We use it as a reference to help us find the value of trigonometric functions. Degrees follow a counter-clockwise pattern from 0 to 360 degrees. Values of cosine are represented by x-coordinates. Values of sine are represented by y-coordinates.Explore math with our beautiful, free online graphing calculator.
