# JavaScript | Math.sinh() function

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)`

Parameter:

• Here the parameter p is a number for which the value of hyperbolic sine is going to be calculated.
• Return value:

• It returns the calculated value of the hyperbolic sine of the number.

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```

Errors and Exceptions:

1. 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`
2. 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```

Application:

• 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.
•  `// 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)); ` `    ``+``"
"``; ` `} `

Output:

```> 0
> 1.1752011936438014
