tanh() function for Complex Number in C++

The tanh() function for complex number is defined in the complex header file. This function is the complex version of the tanh() function of cmath header file. This function is used to calculate the complex hyperbolic tangent of complex number z.

Syntax:

template<class T> complex<T> 
         tanh (const complex<T>& z );

Parameter:

z: This method takes a mandaory parameter z which represents the complex number.

Return Value: This function returns the hyperbolic tangent of the complex number z.

Below programs illustrate the tanh() function in C++:

Example 1:

// C++ program to demonstrate 
// example of tanh() function. 
  
#include <bits/stdc++.h> 
using namespace std; 
  
int main () 
{ 
  complex<double> complexnumber (0.0, 1.0); 
  
  // use of tanh() function for complex number 
  cout << "The tanh of " << complexnumber << " is "
                     << tanh(complexnumber) <<endl; 
  
  return 0; 
} 

Output:

The tanh of (0,1) is (0,1.55741)

Example 2:

// C++ program to demonstrate 
// example of tanh() function. 
  
#include <bits/stdc++.h> 
using namespace std; 
  
int main () 
{ 
  complex<double> complexnumber (1.0, 0.0); 
  
  // use of tanh() function for complex number 
  cout << "The tanh of " << complexnumber << " is "
                     << tanh(complexnumber) << endl; 
  
  return 0; 
} 

Output:

The tanh of (1,0) is (0.761594,0)
