Unlock the Power of Hyperbolic Cosine with JavaScript’s Math.cosh() Method

Understanding the Syntax

The Math.cosh() method is a static method, which means you access it using the class name Math. The syntax is straightforward:

Math.cosh(number)

where number is the value whose hyperbolic cosine you want to calculate.

What to Expect: Return Values and Parameters

The Math.cosh() method takes a single parameter: the number whose hyperbolic cosine you want to calculate. In return, it provides one of two possible values:

• The hyperbolic cosine of the given number
• NaN (Not a Number) if the input is non-numeric

Putting it into Practice: Examples and Results

Let’s see the Math.cosh() method in action:

console.log(Math.cosh(-1)); // Output: 1.5430806348152437
console.log(Math.cosh(0)); // Output: 1
console.log(Math.cosh(2)); // Output: 3.7621956910836314

Infinity and Beyond: Exploring Edge Cases

What happens when you input infinity or non-numeric values? Let’s find out:

console.log(Math.cosh(Infinity)); // Output: Infinity
console.log(Math.cosh(-Infinity)); // Output: Infinity
console.log(Math.cosh("Harry")); // Output: NaN
