ASIN function

Description

Arcsine function. ASIN(x) returns the arcsine of x. The arcsine function is the inverse function of the sine function and calculates the angle for a given sine. x must be in the range [-1..1]. The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function.

The argument x can be a real number, a complex number, or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the ASIN function applied to all elements.
