Python cosh

by

The Python cosh function is one of the Python Math function, which calculates the Trigonometric Hyperbolic Cosine for the specified expression. In this section, we discuss how to use cosh function in Python Programming language with 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 hyperbolic Cosine value.

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

Python cosh Function Example

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

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

# Python COSH 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'))

OUTPUT

Python COSH Function

ANALYSIS

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 the cosh Function on Python Tuple and Python List items. If you observe the above screenshot, the cosh function 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 cosh 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 cosh Function on the string value, and it returns TypeError.

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