Unlock the Power of Hyperbolic Cosine with JavaScript’s Math.cosh() Method
When working with mathematical functions in JavaScript, having a solid understanding of the Math.cosh() method is essential. This powerful tool allows you to calculate the hyperbolic cosine of a given number, opening up a world of possibilities for your coding projects.
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:
- Example 1: Calculating Hyperbolic Cosine
- Input:
-1(negative number) → Output:1.5430806348152437 - Input:
0(zero) → Output:1 - Input:
2(positive number) → Output:3.7621956910836314
- Input:
Infinity and Beyond: Exploring Edge Cases
What happens when you input infinity or non-numeric values? Let’s find out:
- Example 2: Infinity Values
- Input:
Infinity→ Output:Infinity - Input:
-Infinity→ Output:Infinity
- Input:
- Example 3: Non-Numeric Argument
- Input:
"Harry"(string) → Output:NaN
- Input:
