Polar and Cartesian curves are two fundamental ways of describing geometric shapes, each based on a different coordinate system. In the Cartesian system, every point is described using a horizontal position and a vertical position, usually called x and y. Curves are often written as y depending on x, which makes this system especially useful for studying functions, slopes, and rates of change. Many familiar shapes, such as straight lines, parabolas, and circles, are naturally expressed in Cartes

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
