## Inverse Tangent — from Wolfram MathWorld

mathworld.wolfram.com19/11/2020 · The principal value of the **inverse tangent** is implemented as **ArcTan**[z] in the Wolfram Language. In the GNU C library, it is implemented as atan ( double x ). The **inverse tangent** is a multivalued function and hence requires a branch cut in the complex plane , which the Wolfram Language ‘s convention places at and .
