@stdlib/math-base-special-coth

coth

Compute the hyperbolic cotangent of a number.

Installation

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

Usage

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

coth( x )

Computes the hyperbolic cotangent of a number (in radians).

var v;

v = coth( 0.0 );
// returns Infinity

v = coth( 2.0 );
// returns ~1.0373

v = coth( -2.0 );
// returns ~-1.0373

v = coth( NaN );
// returns NaN

Examples

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

var x = linspace( -10.0, 10.0, 100 );

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