Math 337 Introduction to Partial Differential Equations

Winter 2009

Announcements

Assignments; Study guides; Lecture Notes.

Last Announcement. We have the following distribution of the overall grades:

A+	A	A-	B+	B	B-	C+	C	C-	D+	D	F
7	13	6	11	4	7	5	2	2	2	0	0

The average GPA is 3.24. Thank you all for your hard work. Have a nice vacation.

Office hours: Tue Apr. 14 8:30am – 4:30pm. Or by appointments.
Solution to Homework 8 is here. The average for Homework 7 is 32.27 out of 40. The average for Homework 8 is 32.5 out of 40. The notes for the review lectures are available here.
Solution to Homework 7 is here. Lecture notes for the last week are available in Lecture Notes section.
HW8 is due Apr. 7 2pm now. It will be returned Wednesday Apr. 8 in class.
Homework 8 has been posted in Assignments. It is due next Monday Apr.6 4pm. Will be returned Wednesday Apr. 8 in class. The first two problems worth 15 pts each and the last one 10 pts.
Solution to Homework 6 is here. The average of HW6 is 31.77.
There is a mistake in HW7. Problem 12 f) should belong to “intermediate”, not “basic”. And problem 16 should not be required. To remedy this, I will ask the grader to assign 30 pts to the first two problems. So:

HW7 has 3 problems only: 11 c), 12 d) 15 pts each; 12 f) 10 pts.

To make sure that no effort is wasted, anyone who gives a reasonably correct treatment of problem 16 will receive extra points.

Sorry for any inconvenience.
Homework 7 posted in Assignments. Due Apr. 3 2pm. Lecture notes for the past week are available in Lecture Notes section.
Homework 6 posted in Assignments. Due Mar. 27 2pm. Lecture notes for the past two weeks are available in Lecture Notes section. Solution to Homework 5 is here. The average of HW5 is 31 out of 40.

Final grades are assigned according to the University of Alberta letter grading systems, based on relative class standing in terms of overall performance. Suggested grade distribution will be considered.

Homework
- Approximately one homework assignment per week.
- Homeworks will be posted on Fridays, and will be due 2pm the next Friday. An assignment box will be set up on Jan. 14, 2009. The homework will be returned in class on Fridays.
- No late assignments will be accepted. Exceptions may be given to students with legitimate reasons (illness etc.) after a discussion with the instructor. (Proof is required)
- Collaboration is encouraged.
Midterm and Final
- Midterm: Monday Feb. 23, 2009 (right after the reading week). In class. No early or makeup midterm.
- Final: TBA. Makeup final may be provided according to department policies.
- Exams are closed book/notes, no electronic devices are allowed.
- Collaboration is forbidden for exams.
Addition Information on Homeworks and Exams
- Problems in exams will be from the exercises and examples in the textbook.
- All exercises in the textbook will be divided into four categories: basic, intermediate, advanced, not required. The sections in the textbook will be divided into two categories: required, not required. All the examples in required sections are automatically categorized as “basic”.
- Each homework will have 4 problems, 3 “basic” ones and 1 “intermediate” problem.
- In the exams, 75% of the points will be from “basic” problems, 25% from “intermediate” problems, and an extra 25% from “advanced” problems.
