**Math.sinh()** is an inbuilt function in JavaScript which is used to calculate the value of hyperbolic sine of a number.

**Syntax:**

Math.sinh(p)

- Here the parameter p is a number for which the value of hyperbolic sine is going to be calculated.
- It returns the calculated value of the hyperbolic sine of the number.

**Parameter:**

**Return value:**

**Examples:**

Input:Math.sinh(0)

Output:0

**Explanation:**

Here formula for calculating hyperbolic sine of any number is : The number **e** is a mathematical constant having an approximate value equal to **2.718**.

In the same way hyperbolic sine of any number can be calculated just after replacing p with the desired number.

Input:Math.sinh(15)

Output:1634508.6862359024

**Explanation:**

Here same as above calculation, when we put 15 instead of p then the value becomes as output shown above.

**Let’s see some JavaScript code:**

`// Printing hyperbolic sine of some numbers ` `// taken as paramter of Math.sinh() function. ` `console.log(Math.sinh(0)); ` `console.log(Math.sinh(1)); ` `console.log(Math.sinh(5)); ` `console.log(Math.sinh(22)); ` `console.log(Math.sinh(-2)); ` `console.log(Math.sinh(4)); ` |

**Output:**

> 0 > 1.1752011936438014 > 74.20321057778875 > 1792456423.065796 > -3.626860407847019 > 27.28991719712775

- It is an error case because complex number can not be taken as the parameter of the function only integer value can be taken as the parameter.
`// complex number can not be calculated as the hyperbolic sine.`

`console.log(Math.sinh(1 + 2i));`

**Output:**Error: Invalid or unexpected token

- Other than integer nothing is accepted as the parameter of the function that is why here string as the parameter gives NaN i.e, not a number.
`// Any string value as the parameter of the function`

`// gives NaN i.e, not a number`

`// because only number can be used as the parameters.`

`console.log(Math.sinh(`

`"geeksforgeeks"`

`));`

`console.log(Math.sinh(`

`"gfg"`

`));`

**Output:**> NaN > NaN

**Errors and Exceptions:**

- Its practical application is that whenever we need to find the value of hyperbolic sine of a number that time we take the help of Math.sinh() function in JavaScript.

**Application:**

`// Printing hyperbolic sine of some numbers from 0 to 9 ` `// taken as paramter of Math.sinh() function. ` `for` `(i = 0; i < 10; i++) { ` ` ` `console.log(Math.sinh(i)); ` ` ` `+` `"<br>"` `; ` `} ` |

**Output:**

> 0 > 1.1752011936438014 > 3.626860407847019 > 10.017874927409903 > 27.28991719712775 > 74.20321057778875 > 201.71315737027922 > 548.3161232732465 > 1490.4788257895502 > 4051.54190208279
