Module at a Glance How to complete this module:

Cell description

We begin our study of two dimensional nonlinear dynamical systems, and extend our knowledge of one-dimensional flows and two-dimensional linear flow to nonlinear systems.

Objectives

By the end of this module, you will be able to:

  • Illustrate fixed points, orbits, trajectories near fixed points and orbits.
  • Judge stability of fixed points and orbits.
  • Linearize a nonlinear system in order to approximate a phase portrait near a fixed point of a corresponding linear system.
  • Consider the population dynamics of competitive species rabbits and sheep.

How to complete this module:

  1. Watch the video lectures 6A through 6E. 
  2. Complete the reading assignment.
  3. Respond to the discussion board question.
  4. Complete the assignment.
