#### Parameters

Term | Definition |
---|---|

number | Required. The angle in radians for which you want the sine. |

## Return value

Returns the sine of the given angle.

## Remarks

If your argument is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians.

## Example

Formula | Description | Result |
---|---|---|

=SIN(PI()) | Sine of pi radians (0, approximately). | 0.0 |

=SIN(PI()/2) | Sine of pi/2 radians. | 1.0 |
