Syntax of cosh() Function

The syntax of cosh() function in Python is:

math.cosh(x)

Here x is the input value.

 

Parameters of cosh() Function in Python

x – Where x is an angle that is use as an argument. This parameter is required.
Note: If the x parameter is not a number, cosh() function will return an Error. If the passed number outside the range, the compiler will show a math range error.

 

Compatibility

cosh() function is available and compatible with both Python 2.x and 3.x. This function is a part of python standard math library.

 

Return Value of cosh() Function in Python

cosh() function returns the hyperbolic cosine of x which is an input value (angle) that a user passed to find its hyperbolic cosine.

 

Python cosh() Function Example

# import math library
import math
print(math.cosh(-0.2))
print(math.cosh(0))
print(math.cosh(0.2))
print(math.cosh(120))
print(math.cosh(1.336))
