Excel SIN Function

Excel SIN function
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 

The SIN function expects radians. To supply an angle to SIN in degrees, multiply the angle by PI()/180 or use the RADIANS function to convert to radians. For example, to get the SIN of 30 degrees, you can use either formula below:

=SIN(30*PI()/180)
=SIN(RADIANS(30))
