# JavaScript | Math.cosh() function

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

Syntax:

Math.cosh(p)

Parameter: This function accepts single parameter p, which is 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.

Examples:

Input  : Math.cosh(0)
Output : 1


Explanation:
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.   In the same way, hyperbolic cosine of any number can be calculated just after replacing p with the desired number.

Input  :Math.cosh(12)
Output :81377.39571257407


Explanation:
Here same as above calculation, when we put 12 instead of p then the value becomes as output shown above.

Let’s see some JavaScript code:

• Example 1:

 

Output:

 1
1.5430806348152437
1
1792456423.065796
3.7621956910836314
27.308232836016487

• Example 2: Errors and Exceptions, 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.

 

Output:

Error: Invalid or unexpected token
• Example 3: 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.

 

Output:

NaN
NaN

• Application: Its 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() function in JavaScript.
Example:

 

Output:

1
1.5430806348152437
