Description: Get the arccosine of a number
Arccos is a mathematical function that finds the angle whose cosine is a given number, essentially reversing the cosine function; for a value x (between -1 and 1), arccos(x) gives you the angle (in radians, usually between 0 and π) that produces that cosine. It's written as arccos(x) or cos⁻¹(x) and is used when you know the ratio of the adjacent side to the hypotenuse in a right triangle but need the angle itself.
