Math.sinh()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The Math.sinh() static method returns the hyperbolic sine of a number. That is,

\mathtt{\operatorname{Math.sinh}(x)} = \sinh(x) = \frac{\mathrm{e}^x - \mathrm{e}^{-x}}{2}

Try it

console.log(Math.sinh(0));
// Expected output: 0

console.log(Math.sinh(1));
// Expected output: 1.1752011936438014

console.log(Math.sinh(-1));
// Expected output: -1.1752011936438014

console.log(Math.sinh(2));
// Expected output: 3.626860407847019

Syntax

Math.sinh(x)

Parameters

x: A number.

Return value

The hyperbolic sine of x.

Description

Because sinh() is a static method of Math, you always use it as Math.sinh(), rather than as a method of a Math object you created (Math is not a constructor).

Examples

Using Math.sinh()

Math.sinh(-Infinity); // -Infinity
Math.sinh(-0); // -0
Math.sinh(0); // 0
Math.sinh(1); // 1.1752011936438014
Math.sinh(Infinity); // Infinity
