JavaScript Math.cosh()
Syntax & Examples

Math.cosh() static-method

The Math.cosh() method in JavaScript returns the hyperbolic cosine of a number (x). It is a static method of Math, meaning it is always used as Math.cosh() and not as a method of a Math object created (Math is not a constructor).

Syntax of Math.cosh()

The syntax of Math.cosh() static-method is:

Math.cosh(x)

This cosh() static-method of Math returns the hyperbolic cosine of x.

Parameters

ParameterOptional/RequiredDescription
xrequiredA number for which to return the hyperbolic cosine.

Return Type

Math.cosh() returns value of type Number.


✐ Examples

1 Using Math.cosh() with a positive number

In this example, we use the Math.cosh() method to find the hyperbolic cosine of 1.

For example,

  1. We call Math.cosh() with 1 as the argument.
  2. The method returns the hyperbolic cosine of 1.
  3. We log the result to the console using console.log().

JavaScript Program

console.log(Math.cosh(1));

Output

1.5430806348152437

2 Using Math.cosh() with zero

In this example, we use the Math.cosh() method to find the hyperbolic cosine of 0.

For example,

  1. We call Math.cosh() with 0 as the argument.
  2. The method returns the hyperbolic cosine of 0.
  3. We log the result to the console using console.log().

JavaScript Program

console.log(Math.cosh(0));

Output

1

3 Using Math.cosh() with a negative number

In this example, we use the Math.cosh() method to find the hyperbolic cosine of -1.

For example,

  1. We call Math.cosh() with -1 as the argument.
  2. The method returns the hyperbolic cosine of -1.
  3. We log the result to the console using console.log().

JavaScript Program

console.log(Math.cosh(-1));

Output

1.5430806348152437
