Math.sinh()

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

π™ΌπšŠπšπš‘.πšœπš’πš—πš‘ ( 𝚑 ) = sinh ( x ) = e x βˆ’ e βˆ’ x 2 \mathtt{\operatorname{Math.sinh}(x)} = \sinh(x) = \frac{\mathrm{e}^x - \mathrm{e}^{-x}}{2}

Try it

Syntax

js
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()

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