polar() function for complex number in C++

The polar() function for complex number 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.

Returns: This function returns a complex number which is obtain by phase angle and magnitude.

Below program illustrate the above function:-

code

// 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;
}
