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.
