csch

Compute the hyperbolic cosecant of a number.

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 ] ) );
}
