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 Mathe 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.

 

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.

 

Output:

NaN
NaN


Prgram 3: It’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.
Example:

 

Output:
