Python Program for tanh() Function

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

The math.tanh() method returns a number’s hyperbolic tangent.

Syntax:

math.tanh(x)

Parameters:

x: This is Required. It is a number for which the hyperbolic tangent must be calculated. If the value is not a number, a TypeError is returned.

Return Value:

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

The tanh() function returns the hyperbolic Tangent value if the number argument is positive or negative.
The tanh() function returns TypeError if it is not a number.

Examples:

Example1:

Input:

Given first number = 7
Given second number = 5.5

Output:

The result after applying tanh() function on above given first number 7  =  0.9999983369439447
The result after applying tanh() function on above given second number 5.5  =  0.9999665971563038

Example2:

Input:

Given first number = 2
Given second number = 1

Output:

The result after applying tanh() function on above given first number 2  =  0.9640275800758169
The result after applying tanh() function on above given second number 1  =  0.7615941559557649

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.tanh() function to the given first number to get the hyperbolic tangent value of a given number.
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.tanh() 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 = [-1, 1, 3, 0.8]
# Give the first number as static input and store it in another variable.
gvn_numb1 = 7
# Apply math.tanh() function to the given first number to get the hyperbolic
# tangent value of a given number.
# Store it in another variable.
fnl_rslt = math.tanh(gvn_numb1)
# Print the above result
print("The result after applying tanh() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = 5.5
print("The result after applying tanh() function on above given second number",
      gvn_numb2, " = ", math.tanh(gvn_numb2))
# Apply math.tanh() function to the given list element and print it.
print(
    "The result after applying tanh() function on given list element gvnlst[1] = ", math.tanh(gvn_lst[1]))

Output:

The result after applying tanh() function on above given first number 7  =  0.9999983369439447
The result after applying tanh() function on above given second number 5.5  =  0.9999665971563038
The result after applying tanh() function on given list element gvnlst[1] =  0.7615941559557649

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.tanh() function to the given first number to get the hyperbolic tangent value of a given number.
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.tanh() 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.tanh() function to the given first number to get the hyperbolic
# tangent value of a given number.
# Store it in another variable.
fnl_rslt = math.tanh(gvn_numb1)
# Print the above result
print("The result after applying tanh() 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 tanh() function on above given second number",
      gvn_numb2, " = ", math.tanh(gvn_numb2))
# Apply math.tanh() function to the given list element and print it.
print(
    "The result after applying tanh() function on given list element gvnlst[2] = ", math.tanh(gvn_lst[2]))

Output:

Enter some random List Elements separated by spaces = 2 3 10 4 1
Enter some random number = 2
The result after applying tanh() function on above given first number 2.0 = 0.9640275800758169
Enter some random number = 1
The result after applying tanh() function on above given second number 1.0 = 0.7615941559557649
The result after applying tanh() function on given list element gvnlst[2] = 0.9999999958776927
