tanh

Compute the hyperbolic tangent of a number.

Usage

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

tanh( x )

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

var v = tanh( 0.0 );
// returns 0.0

v = tanh( -0.0 );
// returns -0.0

v = tanh( 2.0 );
// returns ~0.964

v = tanh( -2.0 );
// returns ~-0.964

v = tanh( NaN );
// returns NaN

Examples

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

var x = linspace( -4.0, 4.0, 100 );
var i;

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