Last updated: 20 May 2022

    - ACot         (arccotangent = angle whose cotangent is a specified value)
                        NOTE: cotangent = 1 / tangent = adjacent / opposite in right-angled triangle
    - ASec         (arcsecant = angle whose secant is a specified value)
                        NOTE: secant = 1 / cosine = hypotenuse / adjacent in right-angled triangle
    - ACsc         (arccosecant = angle whose cosecant is a specified value)
                        NOTE: cosecant = 1 / sine = hypotenuse / opposite in right-angled triangle
