The ACOS() function returns the arc-cosine (inverse cosine) of a value.

 

 

Format

 

ACOS(expr)

 

where

 

exprevaluates to a number or a numeric array.

 

 

The ACOS() function returns the arc-cosine of expr. Angles are measured in degrees.

 

If expr is a numeric array (a dynamic array where all elements are numeric), the ACOS() function operates on each element in turn and returns a numeric array with the same structure as expr.

 

 

Examples

 

ANGLE = ACOS(ADJ / HYP)

 

This statement finds the angle with cosine equal to the value of ADJ / HYP and assigns this to variable ANGLE.
