Description: Get the arctangent of a number

Arctangent (arctan or tan⁻¹) is the inverse function of the tangent, meaning if \(\tan (x)=y\), then \(\arctan (y)=x\), giving you the angle (x) whose tangent is a specific value (y), often used in physics, engineering, and game development to find angles from slopes or vectors. It answers the question, "What angle produces this ratio of opposite side to adjacent side?" (or rise over run)
