19 | Non-Linear Dynamics
By the end of this section, you should
Understand how non-linear systems may behave much differently than linear systems
Trajectories can vary wildly due to small changes in initial values or parameters
Understand what phase plane is and how it is created
Understand what is meant by chaos and how it differs from “randomness”
