      • Recommended for you
    • Professionals: Professionals in industries such as computer graphics, physics, and engineering may rely on the arctan function in their work.

      • The arctan function is the inverse of the tangent function. While the tangent function returns a value between -∞ and ∞, the arctan function returns an angle in radians whose tangent is equal to the input value.

    • The arctan function is a one-to-one function. While it is true that the arctan function is one-to-one, it has a periodic nature.

      • The arctan function, denoted as arctan(x), is the inverse of the tangent function. It returns the angle whose tangent is a given number. In other words, if y = tan(x), then x = arctan(y). The arctan function works by taking the input value x and returning the angle in radians whose tangent is equal to x. For example, if x = 3, the arctan function returns the angle whose tangent is 3.
