Python math.atanh() method

math.atanh() method is a library method of math module, it is used to get the hyperbolic arc tangent of given number in radians, it accepts a number and returns hyperbolic arc tangent.

Note: math.atanh() method accepts only numbers, if we provide any number which is not in the range it returns a ValueError"ValueError: math domain error", if we provide anything else except the number, it returns error TypeError"TypeError: a float is required".

Syntax of math.atanh() method:

    math.atanh(x)

Parameter(s): x – is the number whose hyperbolic arc tangent to be calculated.

Return value: float – it returns a float value that is the hyperbolic arc tangent value of the number x.

Example:

    Input:
    x = .99

    # function call
    print(math.atanh(x))

    Output:
    2.6466524123622457

Python code to demonstrate example of math.atanh() method

# Python code to demonstrate example of 
# math.atanh() method

# importing math module
import math 

# number 
x = -0.23
print("math.atanh(",x,"): ", math.atanh(x))

x = 0
print("math.atanh(",x,"): ", math.atanh(x))

x = .99
print("math.atanh(",x,"): ", math.atanh(x))

Output

math.atanh( -0.23 ):  -0.2341894667593668
math.atanh( 0 ):  0.0
math.atanh( 0.99 ):  2.6466524123622457

ValueError example

# Python code to demonstrate example of 
# math.atanh() method with exception

# importing math module
import math 

# number 
x = -1
print("math.atanh(",x,"): ", math.atanh(x))

Output

Traceback (most recent call last):
  File "/home/main.py", line 9, in <module>
    print("math.atanh(",x,"): ", math.atanh(x))
ValueError: math domain error

TypeError example

# Python code to demonstrate example of 
# math.atanh() method with exception

# importing math module
import math 

# number 
x = "2"
print("math.atanh(",x,"): ", math.atanh(x))

Output

Traceback (most recent call last):
  File "/home/main.py", line 9, in <module>
    print("math.atanh(",x,"): ", math.atanh(x))
TypeError: a float is required
