Description

The cos command is used to calculate the cosine for any input angle. The input units are in degrees.

Picture the unit circle (a circle of radius 1.0 centered about the origin). If you were to imagine a unit vector rotating inside of the unit circle, the angle (in degrees) that the unit vector makes with the positive x-axis is the input argument theta. The x-coordinate of the endpoint of the unit vector is the return value of the cos function.
