What is Meant by the Arctan?

In mathematics, the arctan is the inverse trigonometric function. It is the inverse function of the tangent function. The arctan function will return the angle whose tangent value is given. The function is represented by “arctan x”. It is also represented by tan-1 x. The angles can be computed in terms of both degrees and radians. We know that the tangent function is a function which is the ratio of the opposite side to the adjacent side.
