## 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
|
||
|
|
```
