Course Webpage:
We have a course webpage with tons of extra material, including java
applets graphing the solutions, animations, background of many models,
online tutorial of differential equations. All quizzes, test answer keys
and practice tests will be available at the section website, also the answers
to even number homework problems. Check the section website at least once
a week for new course information. A lot of files are available in Adobe
Acrobet (pdf) format. If you do not know how to view or print these files,
please ask your instructor or computer lab assistant for help.
Meeting Times and places: MWF 1212:50pm, Tucker 131.
Textbook: There is no printed textbook for the course. Lecture notes will be given to you in class, and also available online. Copies of other reading material (selected chapters from other books, selected research papers) will also be distributed in class when needed.
Computer and Calculators: Computer demonstrations will be given in classes sometime, and browsing differential equations related webpages is a fun thing to do and is necessary for your success in this course. Computer software Maple will be used in some homework assignments and in your semester project. Maple is available on all university Win2000 network computers, please visit webpage http://www.wm.edu/IT/labs/ for lab information. Graphing calculator is not necessary for this course, though a simple scientific calculator may be useful for some numerical calculations.
Course Grade:


Tests and Final Exam: We will have two takehome exams during the semester. Each test accounts for 15 points in the semester grade. (total 30%) You will have one week for the takehome tests.
Homework: Homework will be assigned for every lecture (the list will be available from course webpage) and will be collected once a week (sometimes once in two or three weeks). Not all problems will be graded, but all answer keys will be given to you on the website. It is your responsibility to check your answers and make sure you do them correctly. No late homework will be accepted for any reason.
Project and Presentation: Research groups two or three
people will be formed to conduct projects involving modeling some real
world problems using RD equations, and subsequent analysis and computing
on the model will follow. In the week before spring break, your group will
give a presentation on a paper published by othe people about diffusion
model; and in the last week of class, your group will report some your
own research on a subject using the reactiondiffusion models. Each member
in the group should at least do the presentation once. Your group will
also write a short paper for the topic of the second presentation. Successful
projects will also be presented in Undergraduate Research Conference next
fall (for junior students).
