$NPM version$ $Build Status$ $Coverage Status$

Compute the hyperbolic cosecant of a number.

Installation

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

Usage

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

csch( x )

Computes the hyperbolic cosecant of x.

var v = csch( 0.0 );
// returns Infinity

v = csch( 2.0 );
// returns ~0.2757

v = csch( -2.0 );
// returns ~-0.2757

v = csch( NaN );
// returns NaN

Examples

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

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

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