# SIN

Returns the sine of the given angle.

**Syntax**

**SIN**(**number**)

**Number** is the angle in radians for which you want the sine. If your argument is in degrees, multiply it by PI()/180 to convert it to radians.

**Examples**

`SIN(PI())`

equals 1.22E-16, which is approximately 0 (zero). The sine of p is zero.

`SIN(PI()/2)`

equals 1

`SIN(30*PI()/180)`

equals 0.5, the sine of 30 degrees
