polar() function for complex number in C++

The polar() function for complex numbers is defined in the complex header file. The polar function is used to find the complex number from phase angle and magnitude. 

Syntax:

polar(mag, angle)

Parameter:

• mag: It represents the magnitude of the complex number.
• angle: It represents the phase angle.

Return Type: This function returns a complex number which is obtained by phase angle and magnitude. 

Below program illustrate the above function is as follows:

Program 1:

CPP

// C++ program to demonstrate
// example of polar() function.
#include <bits/stdc++.h>
using namespace std;

// driver function
int main ()
{
  cout << "The complex number whose magnitude is 4.0";
  cout << " and phase angle 1.5";

  // use of polar() function
  cout << " is " << polar (4.0, 1.5) << endl;

  return 0;
}

Output:

The complex number whose magnitude is 4.0 and phase angle 1.5 is (0.282949,3.98998)

Time Complexity: O(1)
Auxiliary Space: O(1)

Program 2:

CPP

// C++ program to demonstrate
// example of polar() function.
#include <bits/stdc++.h>
using namespace std;

// driver function
int main ()
{
  cout << "The complex number whose magnitude is 2.0";
  cout << " and phase angle 0.5";

  // use of polar() function
  cout << " is " << polar (2.0, 0.5) << endl;

  return 0;
}

Output:

The complex number whose magnitude is 2.0 and phase angle 0.5 is (1.75517,0.958851)

Time Complexity: O(1)
Auxiliary Space: O(1)
