This operation calculates the cosine function of its argument. Note that the interpretation of the input argument depends on the whether the DEG (degree) or RAD (radians) mode is on. For real valued arguments, the argument is treated as an angle in degrees if DEG is on. For real valued arguments, the argument is treated as an angle in radians if RAD is on. For complex arguments, the angle is always expected to be in radians.
