| compute the arc sine of a number |
A number between -1.0 and 1.0 (the sine of an angle).
The angle, in radians, whose sine is x. If x is not in the range -1.0 to 1.0, returns NaN.
The arc sine function (sometimes written as
sin-1) is the inverse of the sine
function. It returns the angle whose sine has the specified value, in
radians. The return value is in the range of -
/2 to
/2 radians.
