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

Syntax:

Math.cosh(x)

Parameter: This method accepts 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.
Below example illustrate the Math cosh() method in JavaScript:

• Example 1: Here formula for calculating 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 2: In the same way, 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

More codes for the above method are as follows:

Program 1: Errors and Exceptions, it is an error case because 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

Program 2: Other than integer nothing is accepted as the parameter of the method that is why here-string as the parameter gives NaN i.e, not a number.

## Javascript

 

Output:

NaN
NaN

Program 3: Itâ€™s practical application is that whenever we need to find the value of hyperbolic cosine of a number that time we take the help of Math.cosh() method in JavaScript.

## Javascript

 

Output:
