- Covered today: A brief tour of the complex plane (Appendix G) with particular emphasis on polar
notation for complex numbers. Solving 2nd-order constant coefficient DEs where the auxilliary polynomial has
complex roots.
- For next time:
- Appendix G
- Although we will not collect them, you should make sure that you are able to do all the problems 1-24. If you
are not comfortable with complex numbers, you should do these problems for practice.
