Purpose:
takes a double data type number that represents a sine and
returns a double value that represents the angle of that sine when
measured in radians. (you can convert the radians to degrees by
multiplying them by Math.PI/180)

Syntax:
Asin(double)

Parameters Description
double The expression represents a sine that is
to be converted into radians of an angle. Any
valid System.Double data type number between -1 and +1
if number < -1 or > 1, NaN is returned – NaN stands for Not a Number

Result Data Type Description
double represents the radians of the angle of the sine
that was specified as the input parameter.

Quick Example
Asin(0.5) ‘ Returns .523598775598299
