This gives us a point in the x1-x2 or phase plane that we can plot. Doing this for many values of t will then give us a sketch of what the solution will be doing in the phase plane. A sketch of a particular solution in the phase plane is called the trajectory of the solution.
Definition of Coordinate Plane. Coordinate Plane is a plane formed by the intersection of a horizontal number line with a vertical number line.The horizontal number line is called the x-axis and the vertical number line is called the y-axis. The number lines intersect at their zero points.This point of intersection is called the origin and written as (0, 0).efinition of Coordinate Plane.
