Python Program for cosh() Function

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

The math.cosh() method calculates a number’s hyperbolic cosine (equivalent to (exp(number) + exp(-number)) / 2).

Syntax:

math.cosh(x)

Parameters:

x: This is Required. It is a number for which the hyperbolic cosine 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 cosine.

The cosh function returns the Hyperbolic Cosine value if the number argument is positive or negative.
The cosh function returns TypeError if the number argument is not a number.

Examples:

Example1:

Input:

Given first number = 0.4
Given second number = 1

Output:

The result after applying cosh() function on above given first number 0.4  =  1.081072371838455
The result after applying cosh() function on above given second number 1  =  1.5430806348152437

Example2:

Input:

Given first number = 6.5
Given second number = 2

Output:

The result after applying cosh() function on above given first number 6.5  =  332.5715682417774
The result after applying cosh() function on above given second number 2  =  3.7621956910836314

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.cosh() function to the given first number to get the hyperbolic cosine value of a given number.
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.cosh() 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 = [0.5, 0.2, 1, 0.8]
# Give the first number as static input and store it in another variable.
gvn_numb1 = 0.4
# Apply math.cosh() function to the given first number to get the hyperbolic
# cosine value of a given number.
# Store it in another variable.
fnl_rslt = math.cosh(gvn_numb1)
# Print the above result
print("The result after applying cosh() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = 1
print("The result after applying cosh() function on above given second number",
      gvn_numb2, " = ", math.cosh(gvn_numb2))
# Apply math.cosh() function to the given list element and print it.
print(
    "The result after applying cosh() function on given list element gvnlst[1] = ", math.cosh(gvn_lst[1]))

Output:

The result after applying cosh() function on above given first number 0.4  =  1.081072371838455
The result after applying cosh() function on above given second number 1  =  1.5430806348152437
The result after applying cosh() function on given list element gvnlst[1] =  1.020066755619076

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

Output:

Enter some random List Elements separated by spaces = 2 3 4 1 5
Enter some random number = 6.5
The result after applying cosh() function on above given first number 6.5 = 332.5715682417774
Enter some random number = 2
The result after applying cosh() function on above given second number 2.0 = 3.7621956910836314
The result after applying cosh() function on given list element gvnlst[2] = 27.308232836016487
