Course news

Final exam 502 section (room number corrected!)
Final for section 502 is going to be on Monday, Dec 9, 8-10am in our regular class room. It will be cumulative, with the special attention to fundamental skills with ODEs: 1st order linear, separable and exact; second order linear homogeneous and non-homonogeneous (any of the several methods we learned); linear homogeneous and non-homogeneous systems; nonlinear system analysis of critical points. The exam will have 40 points in total with typically 5 points per question with roughly 2 question per above topic. You are allowed up to 3 pages of formula sheets (2 one-sided is optimal, in my opinion); calculators are ok. We will have a review session on Sunday 4-6pm in Blocker 166. It will be Q&A-style session. As per University regulations, I will not discuss grades over email. The grade breakdown has been posted, any general question regarding grading will be answered in the review session, you can calculate yourself how it applies to your particular grades. It's a math class after all.

Projects for the 200 section
Here is a list of projects available. You will need to choose the ones you'd prefer. Details will be discussed during our lecture on Monday.
10 Nov 2013
Test 2
The second test will cover chapters 3 and 6 (up to and including section 6.4). In particular, you are expected to master second order linear equation using methods of undetermined coefficients, variation of parameters and Laplace transform, and to apply these methods to analysis of mechanical / electrical vibrations.
20 Oct 2013
Test 1
The first test will cover chapters 1, 2, and a part of chapter 3 (up to and including section 3.4). In particular, you are expected to be able to solve linear, separable and exact 1st order equations; be able to use those to solve applied problems; solve homogeneous 2nd order linear with constant coefficients.
