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 will 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 February 5, March 5, and April 9 from 6:30pm to 8:30pm in rooms
to be specified) and a final exam. The final exam is at 10:30am on 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.
