# SIN¶

The **SIN** function calculates the sine (in radians) of the given value.

## Usage¶

`sin(num) : num`

## Examples¶

The following example creates a single NOR row with a column x that calculates the sin of 3.14159 / 2 (which is 90° in radians) resulting in an answer of 1.0.

```
NORROWS 1 | CALC x sin(3.14159/2)
```
