Cos Function

Calculates the cosine of an angle. The angle is specified in radians. The result lies between -1 and 1.

Using the angle Alpha, the Cos-Function calculates the ratio of the length of the side that is adjacent to the angle, divided by the length of the hypotenuse in a right-angled triangle.

Cos(Alpha) = Adjacent/Hypotenuse
