## Usage
|
||
|
|
||
|
```javascript
|
||
|
var sin = require( '@stdlib/math/base/special/sin' );
|
||
|
```
|
||
|
|
||
|
#### sin( x )
|
||
|
|
||
|
Computes the [sine][sine] of a `number` (in radians).
|
||
|
|
||
|
```javascript
|
||
|
var v = sin( 0.0 );
|
||
|
// returns ~0.0
|
||
|
|
||
|
v = sin( 3.141592653589793/2.0 );
|
||
|
// returns ~1.0
|
||
|
|
||
|
v = sin( -3.141592653589793/6.0 );
|
||
|
// returns ~-0.5
|
||
|
```
