[edit] Description
Arc sine is the inverse of the sin() function. Thus, given an fValue that is some ratio of the opposite side to the hypotenuse of a right triangle, asin() returns the appropriate angle (in degrees) of that triangle. asin() returns a value from -90 to 90 or returns zero if fValue is greater than 1 or fValue less than -1.
