# Asinh()

Today, we will discuss the `asinh()` function in PHP. This function is used to get the inverse hyperbolic sine of a number.

## What is the asinh() Function?

The `asinh()` function in PHP is a built-in function that is used to get the inverse hyperbolic sine of a number. The inverse hyperbolic sine is the value whose hyperbolic sine is the given number. The function takes a number as input and returns the inverse hyperbolic sine in radians.

## How to Use the asinh() Function

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

``````<?php
\$number = 1.5;

// Get the inverse hyperbolic sine of the number using the asinh() function
\$inverse_hyperbolic_sine = asinh(\$number);

// Output the inverse hyperbolic sine of the number
echo \$inverse_hyperbolic_sine;
?>``````

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

## Conclusion

The `asinh()` function in PHP is a useful tool for any PHP developer working with trigonometry. By using this function, you can get the inverse hyperbolic sine 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 `asinh()` function in your PHP code.
