SKIP PAST THE ANNOUNCEMENTS if you so desire. ._. (or to near the bottom)

**Dec. 13:**- All the grades are now in Vista. Please read the related information in the Dec. 12 announcement below!
- I corrected some errors in the grades for reviews (and a few homework grades, too). Some reviews were just overlooked; others were recorded in the wrong lines of the spreadsheets. This means that some students' review scores went up a few points while a very few went down (because you had been credited with somebody else's work). I made these changes only in the review total and homework total columns, not in the columns for individual weeks. (If you still have questions, come see me to look at your raw data.)
- Note the invitation (Dec. 11 announcement) to come see me and look at your test.
- I'm still not able to SEND OR RECEIVE e-mail from my office computer.

**Dec. 12:**- I'm having e-mail trouble. If I haven't responded to your message, it's because I haven't seen it yet.
- Grades will be posted soon (before noon on Thursday at latest).
- Final exam scores were disappointing
(median = 133, top = 197, four scores below 100).
Nevertheless, I stick with my statement that you were a very good class.
I curved the
course grades so that a total of
- 607 (86.7%) guarantees an A,
- 513 (73.3%) guarantees a B,
- 420 (60%) guarantees a C

- Homework scores were multiplied by 150/220;
reviewing and class participation scores
were not scaled. Here are the distributions:
- Homework (before scaling), median = 199, high = 263.
- Reviews, median = 35, high = 40.
- Class, median = 7, high = 12.

**Dec. 11:**The solution sheet for the final exam is linked below; please read it. Grades will be reported by Thursday morning at latest. After Thursday noon you are welcome to come by my office to see your exam (not that I will be there often between now and January 14).**Dec. 5:**All the homework (that I know of) has now been processed. Papers will be returned at Thursday's review session, or you can get them from me in my office. (I expect to be there between 1 and 2 on Thursday and at unpredictable times on Friday and Monday.) Notice that the display of homework and reviews contains recent (and fairly substantive) updates for Weeks 3 (3.2.2), 7 (10.4.3), and 10 (2.5.6) as well as Weeks 11 and 12.**Dec. 1:**We agreed on review sessions at 8:00 p.m. on Monday (12/3) and Thursday (12/6). Unless you hear or read otherwise, these will be in BLOC 155 as usual.**Nov. 28:**Announcement of next Math Club meeting (Tuesday, December 4) -- actually an end-of-semester movie party, only loosely math-related. More information added 11/29.**Nov. 26:**Reviewers, return all homework in your possession at the end of Friday's class (Nov. 30) at the latest! That day we will meet in the lab (BLOC 125) so that you can use the computers to finish your reviews, if necessary. For those of you who will have already finished (most of you, I hope) a variety of other fun activities will be available.**Nov. 12:**The 12th and last homework assignment is due**Monday Nov. 26**. There will be no help session that evening (because the room is reserved for something else).**Nov. 5:**Office hour tomorrow (Tues., 11/6) will start late.**Oct. 22:**No help session tonight. Solutions to Test B are now posted below.**Oct. 20:**Tuesday office hour (10/23) may start a bit late.**Oct. 16:**Oops, ignore the announcement right below! (Except for the room change.) Today's office hour will be at 3:00 as usual.**Oct. 15:**Once again, this week, Tuesday's office hour will be at 2, not 3. Remember that henceforth our class will meet in BLOC 120.**Oct. 8:**This week, Tuesday's office hour will be at 2, not 3. Wednesday's hour may start a bit late.**Sep. 28:**Maple demos are now installed below. We will have an evening session Monday (10/1).**Sep. 24:**- There is no evening review session this week.
- We will meet in the computer lab (BLOC 125) this Friday (9/28).
- Answers for Test A are posted below (corrected 9/25).
- By now you should be reading about Fourier transforms (pp. 49-... of notes).

**Sep. 10:**Corrections to homework assignment 2:- The exercise to be done along with 12.5.4 should be 2.3.2(e). (2.3.2(d) is also "related", but 2.3.2(e) is more directly related. If you've already written something sensible about 2.3.2(d), that's OK.)
- In 12.5.3,
*L*should be 10 (misprint in book).

**Sep. 10:**We have BLOCKER 155 reserved for help and review sessions on Mondays (except Nov. 26) 8:00-9:30 p.m.**Sep. 8:**Special schedule for week of Sept. 10-14:- Monday, 9/10: Office hour at 2:00 as usual. Evening help session at 8:00, BLOC 155.
- Tuesday, 9/11: Office hour cancelled.
- Wednesday, 9/12: Office hour moved to 2:00 (instead of 1:00).
- Friday, 9/14: Review session in class.
- Monday, 9/17: Test in class. Please remember to bring your own paper for the test. No evening session that week.

**Sep. 3:**Tonight is our first optional evening session, 8:00 in BLOC 627: more about hreview, TeX, LyX. Revised group membership is posted below. Also, note revised office hours. Finally, I think the hreview alias problem has been solved; more on this tonight and Wednesday.**Aug. 25:**- This is a "stacked" section. That means that Honors students (Sec. 200) and regular students (Sec. 501) are in the same class (because not enough Honors students signed up to make an Honors section). The full implications of that will be discussed in class on Monday (Aug. 27).
