# acot
> Compute the [inverse cotangent][arccotangent] of a number.
## Usage
```javascript
var acot = require( '@stdlib/math/base/special/acot' );
```
#### acot( x )
Computes the [inverse cotangent][arccotangent] of a `number` (in radians).
```javascript
var v = acot( 2.0 );
// returns ~0.4636
v = acot( Infinity );
// returns 0.0
```
## Examples
```javascript
var linspace = require( '@stdlib/array/linspace' );
var acot = require( '@stdlib/math/base/special/acot' );
var x = linspace( -5.0, 5.0, 100 );
var i;
for ( i = 0; i < x.length; i++ ) {
console.log( acot( x[ i ] ) );
}
```
