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

 

 

Example

 

ADJ = HYP * COS(ANGLE)

 

This statement finds the length of the adjacent side of a right angled triangle from the length of the hypotenuse and the angle between these two sides.
