The ASIN() function returns the arc-sine (inverse sine) of a value.
Format: ASIN(expr)
Parameters: expr evaluates to a number or a numeric array.
The ASIN() function returns the arc-sine of expr. Angles are measured in degrees.
If expr is a numeric array (a dynamic array where all elements are numeric), the ASIN() function operates on each element in turn and returns a numeric array with the same structure as expr.
Example:
ANGLE = ASIN(OPP / HYP)
Finds the angle with sine equal to the value of OPP / HYP and assigns this to variable ANGLE.
