# 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 ] ) ); } ```
