Announcements
- The syllabus
- In class on Monday (April 8) we'll do a worksheet on eigenvalues and eigenvectors. I'll talk about these a little beforehand, but it may be helpful to read up on these in 7.3 anyway if you're rusty.
- Office hours next week (April 9) will be Tuesday 3:30-5:30 instead of 3-5. The following week (April 16), they will be Tuesday 2-4. After that, back to normal.
- Here are solutions to a couple problems from Homework 1, along with some basic suggestions for approaching problems that ask you to prove something.
- The midterm will be Friday, May 3.
- Solutions to a few Homework 2 problems, and a few more comments about proofs.
- Extra credit assignment, due by the final.
- We'll have a quiz on Wednesday, May 29.
Homework
- Homework 1, due Wednesday, April 10, and some solutions
- Homework 2, due Wednesday, April 17, and some solutions
- Homework 3, due Wednesday, April 24, and some solutions.
- Homework 4, due Friday, May 3.
- Homework 5, due Wednesday, May 15.
- Homework 6, due Wednesday, May 22.
- Homework 7, due Monday, June 3.
- Homework 8: 10.8 #1, #8, #10, #12, #15. Not due, but these are good practice for the final.

- Quiz 2, Wednesday April 24, and solutions
- Quiz 3 and solutions
- Quiz 4 and solutions
Exams
- Here's a review sheet for the midterm containing the main relevant ideas.
- The midterm and solutions.
- See below for some sample final problems.
- Final exam review sheet.
- The final and solutions.
Resources
- A useful Java applet which draws phase portraits and direction fields for second-order systems of ODEs (use the PPLANE applet)
- Here are two old class webpages where you can find midterms with solutions: one, two. For the most part these will be good practice, but they aren't mine, so there are a few things that are different from what we did. Namely, don't worry about "fundamental matrices", and "fundamental solutions" = "linearly independent solutions".
- The old class pages above have second midterms which include many problems relevant for our final. You can also find final practice problem here (don't worry about 1b, 2b, and 9c).
