ACOS(value)
Value is the real number result of the cosine function taken of an angle you want to find. The legal values of the cosine function are from -1 to 1. An inverse cosine by default will return the normal angle from 0 up to PI. This is because there are several angles which may have an identical value of their cosine. For example, the angles -PI/2, PI/2, 3PI/2, etc., all have a cosine of zero. You can find alternate angles by adding (or subtracting) any multiple of PI radians to the normal angle returned by the inverse cosine function.
You can convert the result of the inverse cosine function from radians into degrees by multiplying it by 180/PI().
