Returns the sine of a given angle.
Cette fonction fonctionne de la même façon dans Google Sheets que dans Excel — même syntaxe et mêmes arguments.
SIN(number)The SIN function calculates the sine of an angle provided in radians. If your angle is in degrees, you must multiply it by PI()/180 or use the RADIANS function to convert it before calculating.
=SIN(PI()/2)Résultat : 1
Calculates the sine of PI/2 radians (90 degrees), which is 1.
=SIN(RADIANS(30))Résultat : 0.5
Converts 30 degrees to radians and calculates the sine, which is 0.5.
This usually happens because the input is in degrees instead of radians; use the RADIANS function to convert it.
