SIN

Returns the sine of the given angle.
Syntax
SIN(number)
Number    is the angle in radians for which you want the sine.
Remark
If your argument is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians.
Example
The example may be easier to understand if you copy it to a blank worksheet.

	A	B
1	Formula	Description (Result)
2	=SIN(PI())	Sine of pi radians (0, approximately)
3	=SIN(PI()/2)	Sine of pi/2 radians (1)
4	=SIN(30*PI()/180)	Sine of 30 degrees (0.5)
5	=SIN(RADIANS(30))	Sine of 30 degrees (0.5)
