acsch

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

Compute the hyperbolic arccosecant of a number.

Installation

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

Usage

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

acsch( x )

Computes the hyperbolic arccosecant of x.

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

v = acsch( -0.0 );
// returns -Infinity

v = acsch( 1.0 );
// returns ~0.881

v = acsch( -1.0 );
// returns ~-0.881

v = acsch( NaN );
// returns NaN

v = acsch( -Infinity );
// returns -0.0

v = acsch( Infinity );
// returns 0.0

Examples

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

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

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

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
