      Question 1/9
      Question 1
      Polar equations of the circle for the given coordinate (x,y) which satisfies the equation given by (x-a)²+(y-b)²=r² where (a,b) is the coordinates of the centre of the circle &r is the radius.
      x = a+ r cos⁡θ, y = b + r sin⁡θ
      x = r cos⁡θ, y = r sin⁡θ
      y = a+r cos⁡θ, x = b + r sin⁡θ
      x = r sin⁡θ, y = r cos⁡θ
