Python math.tanh() method is an efficient way of calculating the hyperbolic tangent of a number in radians. The input parameter must be in radians.
Syntax of Python math.tanh() Method
math.tanh(x)
Parameters
x - Any positive or negative radian value to be operated on.
Return
This method returns a float value representing the hyperbolic tangent of x in radians.
Example 1: Use the math.tanh() Method in Python
import math
x = 90
value = math.tanh(x)
print(f"The hyperbolic tangent of {x} is {value}.")
x = 0
value = math.tanh(x)
print(f"The hyperbolic tangent of {x} is {value}.")
x = -34.5
value = math.tanh(x)
print(f"The hyperbolic tangent of {x} is {value}.")
x = math.pi
value = math.tanh(x)
print(f"The hyperbolic tangent of {x} is {value}.")
x = math.inf
value = math.tanh(x)
print(f"The hyperbolic tangent of {x} is {value}.")
Output:
The hyperbolic tangent of 90 is 1.0.
The hyperbolic tangent of 0 is 0.0.
The hyperbolic tangent of -34.5 is -1.0.
The hyperbolic tangent of 3.141592653589793 is 0.99627207622075.
The hyperbolic tangent of inf is 1.0.
Note that the arguments can be in integers or floats. The values may either be positive or negative.
Example 2: Use the math.tanh() Method to Get the Hyperbolic Tangent of Degrees
import math
print("The hyperbolic tangent of 30 degrees is ", math.tanh(math.radians(30)))
Output:
The hyperbolic tangent of 30 degrees is 0.4804727781564516
We use these methods in mathematical computations related to geometry and have a certain application in astronomical computations.
Example 3: TypeError When Using math.tanh() Method
import math
x = "h"
value = math.tanh(x)
print(f"The hyperbolic tangent of {x} is {value}.")
Output:
Traceback (most recent call last):
File "main.py", line 5, in <module>
value=math.tan(x)
TypeError: must be real number, not str
Note that a TypeError exception may occur if the argument value is not a number.
