**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 https://wustl.instructure.com/courses/114440. In the middle of the
page click on "WebWork." Then click on "Load WebWork in a New Window."

The University has specified that we have three miderm exams
(on September 20, October 18, and November 15 from 6:30pm to 8:30pm in rooms
to be specified) and a final exam. The final exam is 10:30am-12:30am on December 15. 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.

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

The relative weights of the course components are as follows:

Homework: 15%

Attending Recitation: 5%

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:
