Definition

arcus tangent of $x$

arc tangente $x$

$y = arctan x \Leftrightarrow x = tan y$

(for $- π / 2 \leq y \leq π / 2$ )

The function $arctan$ is the inverse of the function $tan$ with the restriction mentioned above.

$arctg x$ should not be used.

$y = arctan x \Leftrightarrow x = tan y$

(pour $- π / 2 \leq y \leq π / 2$ )

La fonction $arctan$ est la réciproque de la fonction $tan$ avec la restriction ci-dessus.

Il convient de ne pas utiliser $arctg x$ .

A mathematical concept as defined in ISO/IEC 80000 Part 2.
