sinh

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

Compute the hyperbolic sine of a double-precision floating-point number.

Installation

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

Usage

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

sinh( x )

Computes the hyperbolic sine of double-precision floating-point number x.

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

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

v = sinh( 2.0 );
// returns ~3.627

v = sinh( -2.0 );
// returns ~-3.627

v = sinh( NaN );
// returns NaN

Examples

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

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

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

C APIs

Usage

#include "stdlib/math/base/special/sinh.h"

stdlib_base_sinh( x )

Computes the hyperbolic sine of double-precision floating-point number x.

double out = stdlib_base_sinh( 2.0 );
// returns ~3.627

out = stdlib_base_sinh( -2.0 );
// returns ~-3.627

The function accepts the following arguments:

x: [in] double input value.

double stdlib_base_sinh( const double x );

Examples

#include "stdlib/math/base/special/sinh.h"
#include <stdio.h>

int main( void ) {
    const double x[] = { -5.0, -3.89, -2.78, -1.67, -0.56, 0.56, 1.67, 2.78, 3.89, 5.0 };
    
    double v;
    int i;
    for ( i = 0; i < 10; i++ ) {
        v = stdlib_base_sinh( x[ i ] );
        printf( "sinh(%lf) = %lf\n", x[ i ], v );
    }
}

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.
