Python tanh – Find Hyperbolic Tangent of Number Using math.tanh()

To find the hyperbolic tangent of a number, we can use the Python tanh() function from the math module.

import math

math.tanh(x)

In Python, we can easily use trigonometric functions with the Python math module. The Python math module allows us to perform trigonometry easily and in addition to regular trigonometry, we have access to the hyperbolic trigonometry functions.

With the Python math module, we can find the hyperbolic tangent of a number easily.

To find the hyperbolic tangent of a number, we can use the Python tanh() function from the math module.

Below is the Python syntax to find the hyperbolic tangent of a number.

import math

math.tanh(x)

The input to the tanh() function must be a numeric value. The return value will be a numeric value between -1 and 1.

import math

print(math.tanh(20))
print(math.tanh(0))
print(math.tanh(-10))

#Output: 
1.0
0.0
-0.9999999958776927

Finding the Inverse Hyperbolic Tangent of a Number in Python

The Python math module also provides us trigonometric functions to find the inverses of the common trigonometric functions. The atanh() function allows us to find the inverse of the hyperbolic tangent of a number.

Below, we show that if we pass a number to tanh() and then call the Python atanh() function, we get back the same number.

import math

print(math.tanh(math.tanh(10)))

#Output: 
10.0

Hopefully this article has been beneficial for you to understand how to use the math tanh() function in Python to find the hyperbolic tangent of a number.
