Systems in the Plane

Why do we care about looking at systems in the plane? Well - we want to know about equilibrium points and how the system behaves around them.

Recall that equilibrium points are fixed. P = Q = 0

Some Loose definitions

Name Definition
Periodic A trajectory loops upon itself
Stable Trajectories converge to a point
Unstable Trajectories diverge from a point
Linear Center An equilibrium point that has orbits around it
Limit Cycle Happens a lot with nonlinear systems. Trajectories are pulled some target trajectory and stay there.
