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

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

{{InteractiveExample("JavaScript Demo: Math.sinh()")}}

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
