cmath is Python built-in module that is used for complex number mathematics. cmath module has a method tanh() that returns hyperbolic  tangent of the complex number passed to it.

Syntax: cmath.tanh(Z)

Parameter: It requires only one parameter i.e the number for which hyperbolic tangent needs to be calculated.

Return: Returns a complex number that is the hyperbolic tangent of the number passed.

Example 1: 

Python3

# Import the Library
import cmath 
  
# Printing the result
print (cmath.tanh(1 + 5j))

                    

Output:

(1.2407479829240697-0.18610947764730415j)

Example 2: In this example real number is passed but the returned result is still a complex number.

Python3

# Import the Library
import cmath 
  
# Printing the result
print (cmath.tanh(1))

                    

Output:

(0.7615941559557649+0j)

Example 3: In this example no argument is passed in this case TypeError will be thrown

Python3

# Import the Library
import cmath 
  
# Printing the result
print (cmath.tanh())

                    

Output:

TypeError: tanh() takes exactly one argument (0 given)
