C Program To Convert Polar To Cartesian Co-ordinates
Formula To Convert Cartesian To Polar Co-ordinates
r = sqrt(x*x + y*y);
OR
r = sqrt( pow(x, 2) + pow(y, 2) );
theta(θ) = atan(y/x);
where x and y are Cartesian co-ordinates.
atan() is the method in math.h library for calculating tan inverse.
Formula To Convert Radian To Degree
degree = radian * (180.0 / PI);
where PI is 3.141592
Source Code: Convert Cartesian To Polar Co-ordinates: C Program
- #include < stdio.h >
- #include < math.h >
- int main()
- {
- float x, y, r, theta;
- const float PI = 3.141592;
- printf("Enter Cartesian Co-ordinates(x, y)\n");
- scanf("%f%f", &x, &y);
- r = sqrt(x*x + y*y);
- theta = atan(y/x); // Radian
- theta = theta * (180.0 / PI); //Radian To Degree Conversion
- printf("Polar Co-ordinates: (r, theta) = (%f, %f)\n", r, theta);
- return 0;
- }
Output:
Enter Cartesian Co-ordinates(x, y)
