arcsin

Returns the inverse sine of x, in that if sin(x)=n, arcsin(n)=x, and the resulting number will be between -pi/2 and pi/2.

NOTE: This will only accept a value between -1 and 1 (anything else will throw an error).

NOTE: This function returns a value in radians, not degrees.

Syntax:

arcsin(x);

Returns:

Real

Example:

val = arcsin(0);

This will set val to 0.
