Python cosh

The Python cosh function calculates the Trigonometric Hyperbolic Cosine for the specified expression. In this section, we discuss how to use the cosh function with an example.

The syntax of the cosh Function in Python Programming Language is

math.cosh(number);

Number: It can be a number or a valid numerical expression for which you want to find a hyperbolic Cosine value.

  • If the number argument is a positive or negative number, the function returns the Hyperbolic Cosine value.
  • If the number argument is not a number, it returns TypeError.

Python cosh Function Example

The cosh Function allows you to find the trigonometric hyperbolic Cosine for the numeric values. In this example, we are going to find the hyperbolic Cosine values for different data types and display the output.

TIP: Please refer to the cos Function article to understand the Cosine Function.

import math

Tup = (1, 2, 3, -4 , 5)
Lis = [-1, 2, -3.5, -4 , 5]

print('Hyperbolic Cosine value of Positive Number = %.2f' %math.cosh(1))
print('Hyperbolic Cosine value of Negative Number = %.2f' %math.cosh(-2))

print('Hyperbolic Cosine value of Tuple Item = %.2f' %math.cosh(Tup[3]))
print('Hyperbolic Cosine value of List Item = %.2f' %math.cosh(Lis[2]))

print('Hyperbolic Cosine value of Multiple Numbers = %.2f' %math.cosh(2 + 9 - 7))

print('Hyperbolic Cosine value of String Value = ', math.cosh('Hello'))
Python COSH Function

First, we used the cosh Function directly on both the Positive integer and negative integer. The following Python statements find the hyperbolic Cosine of the corresponding values.

print('Hyperbolic Cosine value of Positive Number = %.2f' %math.cosh(1))
print('Hyperbolic Cosine value of Negative Number = %.2f' %math.cosh(-2))

Next, we used this hyperbolic cosine Function on Tuple and List items. If you observe the above screenshot, it is working perfectly on them.

print('Hyperbolic Cosine value of Tuple Item = %.2f' %math.cosh(Tup[3]))
print('Hyperbolic Cosine value of List Item = %.2f' %math.cosh(Lis[2]))

Next, we used the math function directly on multiple values.

print('Hyperbolic Cosine value of Multiple Numbers = %.2f' %math.cosh(2 + 9 - 7))

Within the last statement, we tried the cosh Function on the string value, which returns TypeError.

print('Hyperbolic Cosine value of String Value = ', math.cosh('Hello'))
