Click and drag the point (x, y) around the circle in a counterclockwise direction. You will see one full cycle of the tangent function y = tan(x) traced in blue. The degrees that are shown inside the circle correspond with the radian angle measures along the x-axis. For example, 90 degrees = pi/2 radians.
