This page has been identified as a candidate for refactoring of medium complexity.In particular: Use this category for $\tan^{-1}$ in the sense of a multifunction and use Category:Arctangent Function for the inverse of $\tan$'s restriction to $\openint {-\dfrac \pi 2} {\dfrac \pi 2}$. Similarly for the other "inverse" categoriesUntil this has been finished, please leave
`{{Refactor}}` in the code.
Because of the underlying complexity of the work needed, it is recommended that you do not embark on a refactoring task until you have become familiar with the structural nature of pages of $\mathsf{Pr} \infty \mathsf{fWiki}$.To discuss this page in more detail, feel free to use the talk page.When this work has been completed, you may remove this instance of `{{Refactor}}` from the code. |

This category contains results about **Inverse Tangent**.

Definitions specific to this category can be found in Definitions/Inverse Tangent.

The **inverse tangent** is a multifunction defined on $S$ as:

- $\forall z \in S: \inv \tan z := \set {w \in \C: \map \tan w = z}$

where $\map \tan w$ is the tangent of $w$.
