Learning objectives

• Work with a system of differential equations to model populations of two interacting species
• Explain and interpret the phase plane for a 2-dimensional system
• Connect information from the phase plane with information about plots of solutions
• Use pplane to displays solutions of systems of DEs

Before class

• Read Hughes-Hallett 10.6.
• Ponder problems 10.6.2,4,5,6,8,12,20.
• Consult the main points of the lesson

In class

• Answer questions about the project
• Discuss models of interacting populations
• Work with pplane
