Python math.atanh() method is an efficient way of calculating the inverse hyperbolic tangent of a number, x, in radians.
Syntax of Python math.atanh() Method
math.atanh(x)
Parameters
x |
Any positive or negative value in the range -0.99 and 0.99. |
Return
The return type of this method is a float value representing the arctangent of x.
Example Codes: Use math.atanh() Method in Python
import math
x = -0.9
value = math.atanh(x)
print(f"The inverse hyperbolic tangent of {x} is {value}.")
x = 0
value = math.atanh(x)
print(f"The inverse hyperbolic tangent of {x} is {value}.")
x = 0.0086
value = math.atanh(x)
print(f"The inverse hyperbolic tangent of {x} is {value}.")
Output:
The inverse hyperbolic tangent of -0.9 is -1.4722194895832204.
The inverse hyperbolic tangent of 0 is 0.0.
The inverse hyperbolic tangent of 0.0086 is 0.008600212028075704.
Note that the parameter should be a valid number. The values may be either positive or negative.
Example Codes: Code Demonstrates an Error of the math.atanh() Method
import math
x = 1
value = math.atanh(x)
print(f"The inverse hyperbolic tangent of {x} is {value}.")
Output:
Traceback (most recent call last):
File "main.py", line 5, in <module>
value=math.atanh(x)
ValueError: math domain error
Note that a TypeError exception may occur if the argument value is not a float.
Example Codes: Use the Equivalent of the math.atanh() Method
import math
x = 0.8
value = math.atanh(x)
print(f"The inverse hyperbolic tangent of {x} is {value}.")
equation = 0.5 * math.log((1 + x) / (1 - x))
print(f"Using the equation, the inverse hyperbolic tangent of {x} is {equation}.")
Output:
The inverse hyperbolic tangent of 0.8 is 1.0986122886681098.
Using the equation, the inverse hyperbolic tangent of 0.8 is 1.0986122886681098.
You can use either method to calculate the inverse hyperbolic tangent of a number.
