  • Same for nonlinear pendulum, coexisting competing species, non-coexisting competing species

Homework

Whenever a plot is asked for, you can either submit a printout of a computer-generated plot (software of your choice) or sketch a plot by hand.

Exercise with stars next to them are optional for 502 and compulsory for 200 sections.
