The distance between the two points is
The polar coordinate of A is
The polar coordinate of B is
Explanation:
The two points are and
The distance between two points is given by,
Thus, the distance between the two points is
The polar coordinates of A can be written as
Distance =
Substituting , we get,
Distance =
To make the angle positive, let us add 360,
The polar coordinate of A is
Similarly, The polar coordinate of B can be written as
Distance =
Substituting , we get,
Distance =
To make the angle positive, let us add 360,
The polar coordinate of B is
