Year 2 Coordinate Geometry in the (x, y) Plane

In this chapter you will learn how to describe graphs in (x, y) plane, called cartesian equations where the variables x and y are in 2 separate equations, defined by a third variable. These parametric equations are often used to model the path of a moving particle, where its position( given by variables x and y) depends on another variable, such as time, t. A steady pace is recommended for studying this chapter to enable greater focus.
