Cartesian and polar coordinates are two distinct ways of describing the position of points in a plane. In Cartesian coordinates, a point is represented by an ordered pair (x, y), which tells you how far to move horizontally and vertically from the origin. This system is ideal for graphing straight lines and algebraic equations. On the other hand, polar coordinates use a radius r and an angle θ to locate a point, where r is the distance from the origin and θ is the angle from the positive x-axis.

Location - Plot Points on a Cartesian Plane . The Cartesian Plane is a co-ordinate system for locating and labelling unique points on a plane (flat/2D) surface. Co-ordinates indicate the distance from the origin, which is the starting point of each axis, in each direction. . Invention of this system for locating a point in 2D space is attributed to Rene Descartes (also known as Cartesius), a French philosopher, scientist and mathematician who lived in the 17thCentury AD. There is a legend that D
