2280 Problem Notes and Frequently Asked Questions
- Presently, there are none, but the companion book Differential
Equations and Linear Algebra by Edwards-Penney is used for math
2250, and there are numerous notes on those problems. Beware: the
chapters correspond, but have a different order, e.g., Laplace is
earlier in our textbook. Also, some extra chapters appear in our
text, and they will not have 2250 problem notes.
- If I get time to sort this out, then I will, and make available
problem notes keyed to our textbook.
- 2250 Problem Notes. Extra info on dailies.
