Python math.tanh() - Hyperbolic Tangent

Python math.tanh()

math.tanh(x) function returns the hyperbolic tangent of x.

tanh(x) = (e^2x - 1)/(e^2x + 1)

Syntax

The syntax to call tanh() function is

math.tanh(x)

where

ParameterRequiredDescription
xYesA numeric value.

Examples

In the following example, we find the hyperbolic tangent of 5, using tanh() function of math module.

Python Program

import math

x = 5
result = math.tanh(x)
print('tanh(x) :', result)

Output

tanh(x) : 0.9999092042625951
