ArcCos

When applied to a number or an array of numbers, ArcCos produces the arc cosine of the number or an array each element of which is the arc cosine of the corresponding element of the input array, respectively.
It has two variables: X and arcCosX.
arcCosX is measured in radians.

Structure (for scalars):

       X becomes arcCosX

Example:

       0.866026 becomes 0.523598 (which corresponds to 30°)

       1 becomes 0

       (0.866026 1) becomes (0.523598 0)
