NPM version Build Status Coverage Status

Compute the inverse hyperbolic cotangent of a number.

Installation

npm install @stdlib/math-base-special-acoth

Usage

var acoth = require( '@stdlib/math-base-special-acoth' );

acoth( x )

Computes the inverse hyperbolic cotangent of x.

var v = acoth( 2.0 );
// returns ~0.5493

v = acoth( 1.0 );
// returns Infinity

The domain of the inverse hyperbolic cotangent is the union of the intervals (-inf,-1] and [1,inf). If provided a value on the open interval (-1,1), the function returns NaN.

var v = acoth( 0.0 );
// returns NaN

v = acoth( 0.5 );
// returns NaN

Examples

var linspace = require( '@stdlib/array-base-linspace' );
var acoth = require( '@stdlib/math-base-special-acoth' );

var x = linspace( 1.0, 5.0, 100 );

var i;
for ( i = 0; i < x.length; i++ ) {
    console.log( acoth( x[ i ] ) );
}
