# sinh
> Compute the [hyperbolic sine][hyperbolic-sine] of a number.
## Usage
```javascript
var sinh = require( '@stdlib/math/base/special/sinh' );
```
#### sinh( x )
Computes the [hyperbolic sine][hyperbolic-sine] of a `number` (in radians).
```javascript
var v = sinh( 0.0 );
// returns 0.0
v = sinh( -0.0 );
// returns -0.0
v = sinh( 2.0 );
// returns ~3.627
v = sinh( -2.0 );
// returns ~-3.627
v = sinh( NaN );
// returns NaN
```
## Examples
```javascript
var linspace = require( '@stdlib/array/linspace' );
var sinh = require( '@stdlib/math/base/special/sinh' );
var x = linspace( -5.0, 5.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( sinh( x[ i ] ) );
}
```
