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 of two types. There wil be OnLine problems using WebWork. WebWork is handled through wustlkey. The URL is https://webwork.wustl.edu. There will also be handgraded problems which you will submit using another OnLine system called CrowdMark.

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.

The University has specified that we have three miderm exams (on September 12, October 10, and November 14 from 6:30pm to 8:30pm in rooms to be specified) and a final exam (details on the final will be provided later). 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 http://www.math.wustl.edu/seatlookup . The final exam will be on the last day of class. 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. The Math Department mandates that we have three midterms. They are scheduled on September 12, October 10, and November 14 from 6:30pm to 8:30pm in the evening. Details about the final exam will be provided later. You can find out what room to go to and what your seat assignment is for each exam by logging on, on the morning of the exam, to http://www.math.wustl.edu/seatlookup.

2. 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.

3. The Assistant to the Professor for this course is Marie Jose Saad. She will have office hours Mondays and Wednesdays from 2:00pm to 3:30pm in Room 6 in the basement of Cupples I. She will also staff the calculus help room on Wednesdays from 3:30pm to 4:30pm in Lopata 323.

4. I do not allow calculators during exams.

5. Your exam grades may be found on BlackBoard.

6. 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.

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

Here is some essential information about the First Midterm for Math 217.

a) The exam is on September 12 from 6:30pm to 8:30pm. On the morning of the exam, go to http://www.math.wustl.edu/seatlookup to find out your room and seat.

b) You can bring one 4" x 6" card with notes to the exam.

c) You cannot bring a calculator or tablet or computer.

d) There are approximately seven multiple choice questions, one TRUE/FALSE, and two written-out questions (this could vary a bit). For the first eight of these you will be given a ScanTron card to record your answers. The last two you will write out on the exam.

f) Exam grades will be recorded on BlackBoard.
