Text
Differential Equations, Fourth Edition, by Blanchard, Devaney, and Hall.

Course description
From the course catalog:
A first course in ordinary differential equations. First order equations and applications, linear equations with constant coefficients, linear systems, Laplace transforms, numerical methods of solution. Prereq: MATH 223.

We will cover most of the material in chapters 1–3 of the textbook, and selected topics from chapters 4–7.

Homework
There will be homework problem sets for each lecture, mainly taken from the textbook, normally due on Friday. Assignments will be posted on this page (not on Blackboard!).

Students may work together on homework. However, each student must figure out how to write up his or her own solution to be turned in. That means for example that you and a friend may figure out together how to prove a statement, but the written-out solutions you turn in should not be verbatim copies of each other.

All homework assignments are due at 4 p.m. on the listed date. I will not answer questions about homework due on the day it is due. You should deal with any questions you have before then.

Exams
There will be 7 in-class midterm exams, on September 12, September 26, October 10, October 26, November 7, November 19, and December 5. The final exam will be December 11, 4–7 p.m., location TBA. If you have a conflict with one of those exam dates, please let me know as soon as possible so that we can make alternative arrangements. All exams are closed-book and closed-notes with no calculators allowed. (The exams will be written in such a way that you shouldn't need a calculator.)

Grading
Your grade for the semester will be computed as follows:
Homework 22%; each midterm exam 8%; Final exam 22%.

Supplemental instruction for Math 224
Monday and Tuesday, 2–4 p.m. in Rockefeller 306.
