In mathematics, the inverse trigonometric functions (occasionally also called antitrigonometric, [1] cyclometric, [2] or arcus functions [3]) are the inverse functions of the trigonometric functions, …

In trigonometry, arctan refers to the inverse tangent function. It is usually denoted as arctan x and the formula is θ = arctan (Perpendicular / Base)

Jul 23, 2025 · Arctan is defined as the inverse of the tangent function. Arctan (x) is denoted as tan-1(x). There are six trigonometric functions and the inverse of all six functions is repressed …

The arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: Then the arctangent of x is equal to the inverse tangent function of x, …

While we can find the value for arctangent for any x value in the interval [-∞, ∞], there are certain angles that are used frequently in trigonometry (0°, 30°, 45°, 60°, 90°, and their multiples and …

Definition of the arctan function in trigonometry. The inverse of the tangent function. The angle whose tangent is a given number.

A special kind of inverse tangent that takes into account the quadrant in which lies and is returned by the FORTRAN command ATAN2 (y, x), the GNU C library command atan2 (double y, …

Examining the graph of tan (x), shown below, we note that it is not a one to one function on its implied domain. But if we limit the domain to (π 2, π 2) (− 2π, 2π), blue graph below, we …

May 17, 2025 · Understanding the fundamental elements of the arctan function is essential for working with it effectively. The arctan function is defined as the inverse of the tangent function. …
