# Math.sinh()

The Math.sinh() function returns the hyperbolic sine of a number, that can be expressed using the constant e:

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

## Syntax

Math.sinh(x)


### Parameters

x

A number.

### Return value

The hyperbolic sine of the given number.

## 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(0); // 0
Math.sinh(1); // 1.1752011936438014
