The unit circle is a circle of radius one placed at the origin of the coordinate system. This article discusses how the unit circle represents the output of the trigonometric functions for all real numbers.
The unit circle chart shows the position of the points along the circle that are formed by dividing the circle into eight and twelve parts.
