Python math.cosh() Method

Python math.cosh() method is an efficient way of calculating the hyperbolic cosine of a number, x, in radians.

Syntax

math.cosh(x)

Parameters

x Any positive or negative value.

Returns

This method’s return type is a float value representing the hyperbolic cosine of x.

Examples

Use Python math.cosh() Method to Get Hyperbolic Cosine of x in Radians

Code Snippet:

import math

x = -0.9
value = math.cosh(x)
print(f"The hyperbolic cosine of {x} is {value}.")

x = 0
value = math.cosh(x)
print(f"The hyperbolic cosine of {x} is {value}.")

x = 0.0086
value = math.cosh(x)
print(f"The hyperbolic cosine of {x} is {value}.")

x = math.inf
value = math.cosh(x)
print(f"The hyperbolic cosine of {x} is {value}.")

Output:

The hyperbolic cosine of -0.9 is 1.4330863854487745.
The hyperbolic cosine of 0 is 1.0.
The hyperbolic cosine of 0.0086 is 1.0000369802279205.
The hyperbolic cosine of inf is inf.

Note that the parameter should be a valid number. The values may be either positive or negative.

TypeError Using Python math.cosh() Method

Code Snippet:

import math

# entering a string
x = "Hi"
value = math.cosh(x)
print(f"The hyperbolic cosine of {x} is {value}.")

# entering a list
x = [1, 2, 3]
value = math.cosh(x)
print(f"The hyperbolic cosine of {x} is {value}.")

# entering complex numbers
x = 1 + 5j
value = math.cosh(x)
print(f"The hyperbolic cosine of {x} is {value}.")

Output:

Traceback (most recent call last):
  File "main.py", line 5, in <module>
    value=math.cosh(x)
TypeError: must be a real number, not str
Traceback (most recent call last):
  File "main.py", line 5, in <module>
    value=math.cosh(x)
TypeError: must be a real number, not a list
Traceback (most recent call last):
  File "main.py", line 5, in <module>
    value=math.cosh(x)
TypeError: can't convert complex to float

The above code snippets show all possible syntactic errors when using the math.cosh method.
