# JavaScript Math cosh() Method

• Last Updated : 02 Jan, 2023

The Math.cosh() method is used to calculate the value of the hyperbolic cosine of a number.

Syntax:

Math.cosh(x)

Parameter: This method accepts a single parameter as mentioned above and described below:

• x: This parameter holds a number for which the value of hyperbolic cosine is going to be calculated.

Returns: It returns the calculated value of hyperbolic cosine of the number

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

Input : Math.cosh(0)
Output : 1

Example: In the same way, the hyperbolic cosine of any number can be calculated just after replacing p with the desired number. Here the same as the above calculation, when we put 12 instead of p then the value becomes as output shown above.

Input : Math.cosh(12)
Output : 81377.39571257407

Below is an example of the Math cosh() Method.

Example: This example shows the hyperbolic cosine of the numbers passed as a parameter.

## Javascript

 

Output:

 1
1.5430806348152437
1
1792456423.065796
3.7621956910836314
27.308232836016487

Example: Errors and Exceptions, it is an error case because the complex number can not be taken as the parameter of the method only integer value can be taken as the parameter.

## Javascript

 

Output:

Error: Invalid or unexpected token

Example: Other than integer nothing is accepted as the parameter of the method which is why here-string as the parameter gives NaN i.e, not a number.

## Javascript

 

Output:

NaN
NaN

Example: Its practical application is that whenever we need to find the value of the hyperbolic cosine of a number that time we take the help of Math.cosh() method in JavaScript.
