The ASIN function returns a numeric value in radians that approximates the arcsine of argument-1. The type of this function
                  is numeric.

                  - Argument-1 must be class numeric. 
                     	 
                  
- The value of argument-1 must be greater than or equal to -1 and less than or equal to +1.

                  - The returned value is the approximation of the arcsine of argument-1 and is greater than or equal to -pi/2 and less than or
                     equal to +pi/2.
