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:
// 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:
// 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)
