The two different ways of locating a point in a plane are the rectangular coordinates and polar coordinates. In polar coordinate system, each point on a plane is determined by a distance from a reference point and an angle from the reference direction. It is represented by
But in the rectangular coordinate system, each point in a plane is determined by a pair of coordinates and represented in the form of (x, y).
So, in rectangular coordinate system the origin coincides with origin in polar and axis in the rectangular coordinate system is the polar axis in the polar coordinate system because an extended line from the reference point is the axis and it denotes the direction of point from the pole in both the coordinate systems.
So, both representations are similar but their nature will vary.
The pole and the polar coordinate arerepresented as the figure given below.
