“Polar and Cartesian Geometry: Two Perspectives on Position and Space”The Cartesian coordinate system represents points in a plane using two perpendicular axes, typically labeled x and y. Each point is defined by an ordered pair (x, y), which specifies the horizontal and vertical distances from the origin. This system is intuitive for describing locations in grids and rectangular layouts, making it ideal for algebraic equations, linear graphs, and many engineering applications. Cartesian coordin
