# SIN macro

The `SIN` macro is available only in Unica Campaign.

## Syntax

`SIN(data [, units_keyword])`

## Parameters

`data`

The numerical values to compute the sine of. This can be a constant value, a column, a cell range, or an expression evaluating to any of the above. For the format definition of `data`, see the "Macro Function Parameters" section in the chapter in this guide for your product.

`units_keyword`

This optional keyword determines whether the input values and results are interpreted as degrees or radians. Select one of the following:

`RADIAN` - Performs the calculations in radians (default)

`DEGREE` - Performs the calculations in degrees

If this parameter is not specified, the default is radians. (To convert from radians to degrees, divide by `PI` and multiply by 180.)

For more details on using keywords in Unica Campaign, see Format Specifications.

## Description

`SIN` calculates the sine of values in the specified data range. It returns one new column for each input column, each containing the sine of numbers in the corresponding input column.

## Examples

 `TEMP = SIN(PI/2)` or ```TEMP = SIN(PI/2, 0)``` or `TEMP = SIGN(PI/2, RADIAN)` Creates a new column named `TEMP` containing the value one. `TEMP = SIN(V1)` Creates a new column named `TEMP`, where each value is the sine (in radians) of the contents of column `V1`. `TEMP = SIN(V1:V3, 1)` or ```TEMP = SIN(V1:V3, DEGREE)``` Creates three new columns named `TEMP`, `VX`, and `VY`. The values in the `TEMP` column are the sines of the contents of column `V1`, the values of the `VX` column are the sines of the contents of column `V2`, and the values of the `VY` column are the sines of the contents of column `V3`. All values are in degrees. `TEMP = SIN(V1[10:50]:V2)` Creates two new columns named `TEMP` and `VX`, each with values in rows 1-41 (the other cells are empty). The values in column `TEMP` are the sines of the values in rows 10-50 of column `V1`, and the values in column `VX` are the sines of the values in rows 10-50 of column `V2`. All values are in radians.
