# Fonctions trigonométriques et hyperboliques

Cette section décrit les fonctions permettant de réaliser des opérations trigonométriques et hyperboliques. Dans toutes les fonctions, les arguments sont des expressions fournissant des angles mesurés en radians, où x doit être interprété comme un nombre réel.

Tous les angles sont mesurés en radians.

Les fonctions s'utilisent toutes aussi bien dans le script de chargement que dans les expressions de graphique.
