Course Description: The purpose of this course is to learn about the theory and solution of ordinary differential equations. We will learn to recognize and to solve a variety of differential equations, and we will learn a variety of applications to physical and engineering problems.

The course will follow the text rather closely. But it is strongly advised to attend class, as the instructor will offer many ideas and insights not to be found in the book. It is also important to keep up with the homework.

Work Required in the Course: There will be weekly homework assignments using an OnLine system called WebWork. WebWork is handled through wustlkey. The URL is https://work.wustl.edu. The TAs will go over the WebWork problems in the weekly problem sessions. What is nice about WebWork is that it grades your problems in real time so that you get instant feedback. More Information about how to access WebWork will be provided in due course. In fact you can access the first WebWork assignment in the following way: go to canvas and click on Assignments.

The University has specified that we have three miderm exams (on February 7, March 6, and April 10 from 6:30pm to 8:30pm) and a final exam. The final exam is 10:30am-12:30pm May 3. If you cannot make one of these exams then you should tell me (the instructor) at least a week in advance so that other arrangements can be made. You find out your room and seat assigment for each exam by logging on, on the morning of the exam, to https://www.math.wustl.edu/examlookup.

The relative weights of the course components are as follows:

Homework: 20%

Midterm I: 20%

Midterm II: 20%

Midterm III: 20%

Final Exam: 20%

TOTAL: 100%


If you are taking the course Pass/Fail, then the cutoff for a pass is C - or 65 percent.


I will conclude here with a variety of useful information:

1. To access WebWork, you need to go to webwork.wustl.edu and select Math 217. Your username and your password are both your student ID number. The password should be changed as soon as possible.

2. The Assistants to the Professor for this course are Ana Colovic (a.colovic@wustl.edu), Jose Issa Barbara (i.jose@wustl.edu), and John Naughton (j.naughton@wustl.edu). They will have office hours to be announced.

3. I do not allow calculators during exams.

4. Your exam and homework grades may be found on an OnLine system to be announced.

5. Disability Resources: Special accommodations for exams are offered to students who are registered at Disability Resources (DR). Information about DR may be found at http://disability.wustl.edu. Students who desire to take advantage of this service should visit DR early in the semester, well before the first exam.

6. This Web page is the lifeline of the class. Homework assignments, additional course information, corrigenda, exam information, solutions, and other announcements will all be posted here. Bookmark the page and refer to it frequently.
