Summary
The Excel SIN function returns the sine of angle given in radians. To supply an angle to SIN in degrees, multiply the angle by PI()/180 or use the RADIANS function to convert to radians.
Purpose
Get the sine of an angle
Return value
Sine value
Syntax
=SIN (number)
Arguments
Number – The angle in radians for which you want the sine.
Usage notes
To work in degrees rather than radians: SIN(PI()/180) or SIN(RADIANS(number))
