Introduction to dynamical systems. More to come.

We have discussed the following topics:

• Phase portrait of 1-d system (growth with carrying capacity).
• Phase portrait of 2-d system (predator-prey model).
• How to find out fixed points of dynamical systems, and how to solve for them using our own custom-built Newton method, or the fsolve function from Python (Sec 5.5. in the textbook).
• How to plot vector fields / phase portraits of dynamical systems using functions in Sec 5.9 of the textbook.
