# Funzioni trigonometriche e iperboliche

In questa sezione vengono descritte le funzioni per l'esecuzione delle operazioni trigonometriche e iperboliche. In tutte le funzioni, gli argomenti sono espressioni che restituiscono angoli misurati in radianti, in cui x deve essere interpretato come un numero reale.

Tutti gli angoli sono misurati in radianti.

Tutte le funzioni possono essere utilizzate sia nello script di caricamento dei dati che nelle espressioni grafiche.
