Mathematics 401, Sec. 501, Spring, 2009
Last updated Wed 13 May 09
- Announcements
- MaJy 13: Scores and grades are available on Blackboard Vista.
(Go to the bottom of your gradebook page to see the letter grade.)
Some explanations are here.
- May 12: Corrected final exam solutions are posted below.
PLEASE STUDY THEM, especially Qu. 2 (Fourier transform problem) and Qu. 3
(two-dimensional eigenfunction problem). Many of you did not seem to
understand what was being asked in those two problems.
Also, I should have been more careful in algebra in Qu. 4; after the
correction, the coupled ODEs can be solved by the same trick as in
the homework example, contrary to what I thought.
I also fixed typos in the solution to Qu. 5(A).
- Apr. 28: Latest Math Club
announcement (Olympiad movie, May 5)
- Apr. 14: Key for Test B is posted below. I took a problem off
each of Assignments 12 and 13 (see below) and postponed #12 to the
following Monday.
- Apr. 8: appeal to take the NSSE
survey
- Apr. 8:
I reorganized the homework assignments between 2005 and 2006, so some of
the 2005 solutions are not in the "correct" weeks from our present point
of view. I think I have now turned the read permissions on for all the
exercises that have been turned in. In particular, 4 of the problems in
set #10 have solutions in 2005 set #11.
Note also that some defective solutions were never satisfactorily revised;
be sure to check "instructor's comments" in the reports.
- Jan. 31: Note that I've changed the office hours. I will be in
on Tuesday afternoons 2:45-3:45; and at the same time on Thursdays
in test weeks only. Monday and Wednesday hours have not changed.
- Dec. 29: This semester we will NOT do peer review of
homework as in most previous years.

CORRECTION: Ex. 1, part (b), should refer to p. 79, not p. 81.
Also, Qu. 3 concerns a "semi-infinite" plate (0 < x < L, 0 < y <
[infinity]).
