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.
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.
Quizzes
Exams
- Here's a review sheet for the midterm containing the main relevant ideas.
- The midterm 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".
