### Wikipedia

arc tangent

In mathematics, the inverse trigonometric functions (occasionally also called arcus functions, antitrigonometric functions or cyclometric functions) are the inverse functions of the trigonometric functions (with suitably restricted domains). Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.

### ChatGPT

arc tangent

The arc tangent, also known as the inverse tangent function, is a mathematical function that determines the angle whose tangent is a given number. It is typically represented as tan^-1(x) or arctan(x), and it links the ratio of the length of the two sides of a right-angled triangle (opposite to the angle and adjacent to the angle) to the size of the angle. The output or range of the arc tangent function is usually between -90 and 90 degrees, or between -π/2 and π/2 in radians. The arc tangent is distinct in that it gives an output even for input values outside the range of -1 and 1.
