    2280 Problem Notes and Frequently Asked Questions

    1. 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.
    2. If I get time to sort this out, then I will, and make available problem notes keyed to our textbook.
