Course Description

The subject of this is course is an introduction to ordinary differential equations. It is pretty much a natural continuation of what we have learned in calculus.

Calculus II (Math 152) is a prerequisite. A knowledge of Linear Algebra (Math 221) will be a great asset, although it's not a prerequisite.

Textbook

Fundamentals of Differential Equations (sixth edition) by Nagle, Saff and Snider.

We will do essentially all of chapters, 1, 2, 3, 4, 5, 7, 9 plus a little add-on material.

Note: If you happen to own the alternative version of the book that was used in the previous semester, that's OK too. That book was:

Fundamentals of Differential Equations and Boundary Value Problems (fourth edition) by Nagle, Saff and Snider.

The first 10 chapters of the two books are identical and that's good enough for us.

Grading

Your course grade will be calculated based the weights attached to various components as shown in the adjacent table. Letter grades will be determined according to:

if { grade ≥ 85: A}
else if { grade ≥ 75: B}
else if { grade ≥ 65: C}
else if { grade ≥ 55: D}
else F

I will make and grade the exams in a fair and reasonable way, but sorry, no "curving" in this course.

Exam 1 and Exam 2 will cover approximately the first third and second third of the course. They will be given in the regularly scheduled classroom.

The Final Exam is comprehensive. It will cover the entire course, however it will put greater emphasis on the material covered in the later parts of the course.

The Final Exam is on May 12, 3:00-5:00, in MP 103.
Note change in time!

Solutions of homework problems assigned during each week are due on the Wednesday of the following week. No late homeworks will be accepted, however the two lowest homework grades will be dropped.

I will assign homework problems as I go. Just before or just after each class I will add the new assignments on this page. That way, if you miss a class (tsk, tsk) you can look up the assignments here.
