Cosh()

Today, we will discuss the cosh() function in PHP. This function is used to get the hyperbolic cosine of a number.

What is the cosh() Function?

The cosh() function in PHP is a built-in function that is used to get the hyperbolic cosine of a number. The hyperbolic cosine is the value of (e^x + e^-x) / 2, where x is the number provided as input. The function takes a number as input and returns the hyperbolic cosine of the number.

How to Use the cosh() Function

Using the cosh() function in PHP is very simple. Here is an example of how to use the function:

<?php
$number = 2;

// Get the hyperbolic cosine of the number using the cosh() function
$hyperbolic_cosine = cosh($number);

// Output the hyperbolic cosine of the number
echo $hyperbolic_cosine;
?>

In this example, we set the number as a variable. We then call the cosh() function with the number as a parameter to get the hyperbolic cosine of the number. Finally, we output the hyperbolic cosine of the number to the screen.

Conclusion

The cosh() function in PHP is a useful tool for any PHP developer working with trigonometry. By using this function, you can get the hyperbolic cosine of a number, which can be useful in a variety of applications. We hope that this guide has been helpful in understanding how to use the cosh() function in your PHP code.
