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

𝙼𝚊𝚝𝚑.𝚜𝚒𝚗𝚑(𝚡)=sinh(x)=ex−e−x2\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

jsMath.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()

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