Math 2021 A: Course Information
Announcements for the "remediation" period:
(See further down for announcements made during the period
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,
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
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.)
a) Math geeks: See the Putnam announcement below and also
this file, on the Mathematical
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
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
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
