Math 2021 A: Course Information

Announcements for the "remediation" period:

(See further down for announcements made during the period Sept.-Dec. 2000.)

OK, folks, here are the grades! Have a good life!

103. (8:55 p.m., 26 Feb.)
Folks, I do not have the final grades and exam grades ready quite yet. Look on this web page again tomorrow around 8 p.m.; I will definitely have the marks posted by then. Sorry....

102. (22 Jan., 11:35 p.m.)
Here is a file about sale of previous years' exams in MATH 2021, if you don't get one in class this week or so (I have about four copies each of the exams I sold last month, still).

The second class test will be given in class one week from today, Monday, 29 January. You should know (tentatively, as of tonight) everything done in class up through 26 January. If you are not coming to class, too bad. Find out from someone who is what we have done in class (see course outline, day 1 of class).

Here is a timetable for the classes in MATH 2021 in the additional instruction period. It includes sections of the book to be covered on particular days, and a list of exercises to try in the text but not to hand in. The timetable is only approximate, and will be updated every few days. So keep checking back with it. The second class test will be given roughly two weeks before the end of term. See the York home page and the Registrar's page for dates for this term like last day of class.

101. (12 Jan., 9:40 p.m.)
Here is a first file on what will happen in MATH 2021 in the way of "remediation". Stay tuned for further announcements.


I will put announcements here on a continual basis, in reverse chronological order, numbered and dated.

11. (13 Dec., 3:56 p.m.)
I have finally posted the adjusted marks for Test 2. Go to the link in the announcement below and look at the bottom of the file.

10. (9 Dec., 10:40 p.m.)

Note added 14 January, 2001:

I destroyed the link to this file just now. I don't see why students taking the test late should have the advantage of seeing solutions to it, when students who took the test had seen neither solutions nor problems.

Here is a file of solutions to, and comments about, Test 2. At the bottom of the file are an indication of how I will adjust the grades, and some stats on how people did. People generally did not know what they were supposed to know. It is ALWAYS this way.

10. (8 Dec., 8:05 p.m.)
I apologize hereby to anyone who came to my office at 10 a.m. today expecting to find me there. Somehow I thought I had said I would be there at noon. In fact I believe I appeared about 10:45. Seven people picked up test papers and old exams. Anyone else who came expecting to find me at 10, and who lost a bunch of time for this: I can offer you FREE old exams, and whatever financial compensation you think is right: $20, $40, whatever. And, again, apologies.

Maybe later tonight, and in any case by tomorrow night, I will have test 2 results posted here, and solutions to it. I am in Monday again, and later in the week as well.

9. (10 Nov., 4:40 p.m.)
Here, FINALLY, is a file on Test 1: solutions, comments, marking scheme.

8. (31 Oct., 1:10 a.m.)
Here is an excerpt from e-mails exchanged between a student in our class and Ganong, about problem 7 in section 5.1:

7. (25 Oct., 11:30 p.m.)
This is a postscript to the previous item (28) about the CUPE strike:

Be reassured that I do not intend actively to put students at a disadvantage who do not come to my classes. But no "notes" short of a videotape can capture everything in a lecture. I will do my best to provide good notes of what is done in class. I resent having to do this, but will do it. The fact that I have to do this is not the fault of any students, but of the whole union/management structure at York. I have not followed events closely enough to know how I feel about CUPE's cause (I would not know even if I spent many dozens of hours reading stuff). I know I have a low opinion of York's way of handling labour relations.

I will either use a different marking scheme for students who miss assignments/test, or give extensions of dates for completing those. I may use a mix of the two procedures. Not sure now.

6. (25 Oct., 12:40 p.m.)
In the event of a CUPE strike, I intend to go on teaching all my classes. I will just get off the TTC bus outside the picket lines and walk into campus and teach my classes.

Senate rules require me to make class notes or some such available to students who choose not to cross the picket lines. The last time there was a big strike at York, tons of students took it as a sign that they could just stop coming to classes and would somehow get free marks in the end. That is not how it goes. If your conscience requires you to stay off campus to support CUPE, then by all means do that. If not, come to class as usual. People who miss class will, as always, have a much harder time in my courses than people who do not.

5. (9 Oct., 5:50 p.m.)
Here is a file intended to help folks prepare for our test a week hence.

4. (8 Oct., 11:50 p.m.)
I do not yet have a marking scheme typed into this file, but there are solutions and comments in Assignment 2: solutions, comments, marking scheme. Will get a marking scheme typed in a.s.a.p.

3. (27 Sept., 2:15 a.m.)
Two announcements:

a) Math geeks: See the Putnam announcement below and also this file, on the Mathematical Modelling Competition.

b) Here is a file on Assignment 1: Solutions, comments and marking scheme.

2. (22 Sept., 11 p.m.)
Here are the hours when the MathLab (S525 Ross) is open:
Monday - Thursday 11 a.m. - 4 p.m., Friday noon - 3:30 p.m.
(See the course outline.)

1. (22 Sept., 12:05 p.m.)
Math nerds!! Think about taking the Putnam Exam!

The text is Linear Algebra with Applications, 3rd Edition, by W. Keith Nicholson.

Here is a link to a file on

study groups in mathematics courses

which you may find interesting. The file lives on the Math. Department's Undergraduate page, and was produced over the course of a couple of years as a collaboration between a few professors and upper-year students in the department. It is a little out of date. In particular, you should not at this point send e-mail to any individuals mentioned in that file, since the people involved may well have changed since a year ago.

I also must say that I would not have posted a file with as many errors in it as this one has (and various others linked to it have), but the files are worth looking at if you ignore the (mostly small) mistakes.
