Python math.acosh() - Arc / Inverse Hyperbolic Cosine
Python math.acosh()
math.acosh(x) function returns the arc hyperbolic cosine of x.
acosh(x) = log(x + sqrt(x^2 - 1))
Syntax
The syntax to call acosh() function is
math.acosh(x)
where
Parameter | Required | Description |
---|---|---|
x | Yes | A numeric value. x must be greater than or equal to 1. |
If x is not a valid value for acosh() function, then the function raises ValueError.
Example
In the following example, we find the inverse hyperbolic cosine of 5, using acosh() function of math module.
Python Program
import math
x = 5
result = math.acosh(x)
print('acosh(x) :', result)
Output
acosh(x) : 2.2924316695611777
Summary
In this Python Examples tutorial, we learned the syntax of, and examples for math.acosh() function.
