Python Program for atanh() Function

In the previous article, we have discussed Python Program for asinh() Function
atanh() Function in Python:

The inverse hyperbolic tangent of a number is returned by the math.atanh() method.

Note: It should be noted that the parameter passed in math.atanh() must be between -0.99 and 0.99.

Syntax:

math.atanh(x)

Parameters:

x: This is required. It is a number between -0.99 and 0.99 that is positive or negative. If x is not a number, a TypeError is returned.

Return Value:

Returns a float value representing a number’s inverse hyperbolic tangent.

The atanh function returns the Hyperbolic Arc Tangent value if the number argument is both positive and negative.
The atanh function returns ValueError if it is not between -1 (exclude) and 1 (exclude).
If it is not a number, the atanh function throws a TypeError.

Examples:

Example1:

Input:

Given first number = 0.6
Given second number = -0.8

Output:

The result after applying atanh() function on above given first number 0.6  =  0.6931471805599453
The result after applying atanh() function on above given second number -0.8  =  -1.0986122886681098

Example2:

Input:

Given first number = 0.54
Given second number = -0.9

Output:

The result after applying atanh() function on above given first number 0.54  =  0.6041556029622671
The result after applying atanh() function on above given second number -0.9  =  -1.4722194895832204

Method #1: Using Built-in Functions (Static Input)

Approach:

Import math module using the import keyword.
Give the list as static input and store it in a variable.
Give the first number as static input and store it in another variable.
Apply math.atanh() function to the given first number to get the inverse hyperbolic tangent of a given number
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.atanh() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as static input and store it in a variable.
gvn_lst = [0.25, 0.35, 1, 4]
# Give the first number as static input and store it in another variable.
gvn_numb1 = 0.6
# Apply math.atanh() function to the given first number to get the inverse
# hyperbolic tangent of a given number
# Store it in another variable.
fnl_rslt = math.atanh(gvn_numb1)
# Print the above result.
print("The result after applying atanh() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = -0.8
print("The result after applying atanh() function on above given second number",
      gvn_numb2, " = ", math.atanh(gvn_numb2))
# Apply math.atanh() function to the given list element and print it.
print(
    "The result after applying atanh() function on given list element gvnlst[1] = ", math.atanh(gvn_lst[1]))

Output:

The result after applying atanh() function on above given first number 0.6  =  0.6931471805599453
The result after applying atanh() function on above given second number -0.8  =  -1.0986122886681098
The result after applying atanh() function on given list element gvnlst[1] =  0.36544375427139614

Method #2: Using Built-in Functions (User Input)

Approach:

Import math module using the import keyword.
Give the list as user input using list(),map(),input(),and split() functions.
Store it in a variable.
Give the first number as user input using the float(input()) function and store it in a variable.
Apply math.atanh() function to the given first number to get the inverse hyperbolic tangent of a given number
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.atanh() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as user input using list(),map(),input(),and split() functions.
# Store it in a variable.
gvn_lst = list(map(float, input(
    'Enter some random List Elements separated by spaces = ').split()))
# Give the first number as user input using the float(input()) function
# and store it in a variable.
gvn_numb1 = float(input("Enter some random number = "))
# Apply math.atanh() function to the given first number to get the inverse
# hyperbolic tangent of a given number
# Store it in another variable.
fnl_rslt = math.atanh(gvn_numb1)
# Print the above result.
print("The result after applying atanh() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = float(input("Enter some random number = "))
print("The result after applying atanh() function on above given second number",
      gvn_numb2, " = ", math.atanh(gvn_numb2))
# Apply math.atanh() function to the given list element and print it.
print(
    "The result after applying atanh() function on given list element gvnlst[2] = ", math.atanh(gvn_lst[2]))

Output:

Enter some random List Elements separated by spaces = 0.1 0.2 -0.3 4.4
Enter some random number = 0.54
The result after applying atanh() function on above given first number 0.54 = 0.6041556029622671
Enter some random number = -0.9
The result after applying atanh() function on above given second number -0.9 = -1.4722194895832204
The result after applying atanh() function on given list element gvnlst[2] = -0.30951960420311175
