[edit] Description
Arc cosine is the inverse of the sin() function. Thus, given an fValue that is some ratio of the adjacent side to the hypotenuse of a right triangle, the acos function returns the appropriate angle (in degrees) of that triangle. The acos function returns a value from 0.0 to 180.0.
