## Description

Do you need to calculate the inverse hyperbolic cosine of a given value in Python? The math.acosh() method is your solution! Read this tutorial and learn how to calculate the inverse hyperbolic cosine of a given value with math.acosh() method in Python.

### Definition

The math.acosh() method in Python is used to return the inverse hyperbolic cosine of a given value. In mathematics, the inverse hyperbolic cosine is the function that allows us to calculate arcosh or inverse of hyperbolic cosine and is denoted by ‘acosh’. In Python, this function returns the inverse hyperbolic cosine of ‘x’ array elements.

### Usecase

The use cases of the Python acosh() method are used in maths where we need the inverse of hyperbolic functions. It is also used in the solution of equations.

## Examples with Output

Python’s math.acosh() method takes a number as an argument and returns the inverse hyperbolic cosine of the number. Here are some examples to show you how the math.acosh() method works in Python.

### Example 1: Calculate the inverse hyperbolic cosine of a given value

import math

# given value
x = 2

# inverse hyperbolic cosine of x
y = math.acosh(x)

# print the value of y
print("The inverse hyperbolic cosine of", x ,"is", round(y, 2))

Output: The inverse hyperbolic cosine of 2 is 1.48

### Example 2: Calculate the inverse hyperbolic cosine for the float value

import math

# given value
x = 3.6

# inverse hyperbolic cosine of x
y = math.acosh(x)

# print the value of y
print("The inverse hyperbolic cosine of", x, "is", round(y, 2))

Output: The inverse hyperbolic cosine of 3.6 is 1.78

## Conclusion

In this tutorial, you have learned how to use the math.acosh() method in Python to calculate the inverse hyperbolic cosine of a given value. We’ve also provided some examples in order to make it easier for you to understand how the math.acosh() works.
