Special nonlinear systems

Get inspired:

By the end of this lesson, you should be able to:

  • Explain what a conservative system is.
  • Find a conserved quantity for a conserved system and use it to plot trajectories.
  • Explain what a reversible system is and determine whether a system is reversible.
  • Identify special cases where linear centers are guaranteed to be nonlinear centers

Before class, please:

  • Read Strogatz, Sections 6.5 - 6.7.
  • Read these notes.
  • Check yourself before you wreck yourself (none)

In class, we will:

After class, please:

  • Do post-class problems.
