Final letter grades have been posted. Good work everyone!
(PS--if you checked before 12:45 pm on Thursday, please check again
now--they have been corrected.)
We went over the old final during the review session--here are the
smartboard notes from the review session:
Grades to date have been posted, and here is a copy of last
semester's final exam, plus solutions. Happy to cover any of
this during the review session.
Your exam will have different
questions of course, with some kinds of questions replaced by other
kinds, but this gives a good idea.
Review session-- Tonight at 6:30 to about 7:30, in JEM
366 (just up the hall from our usual classroom). Will mostly
be covering related rates, optimization, and graphing.

Title: Characterizations of Unit-Bar
Dean, Department of Mathematics and Computer Science, Skidmore
Representations of graphs using horizontal bars for vertices and
vertical visibilities for edges have been studied since the mid
1980s, motivated by applications to circuit design and display of
data. Graphs that can be represented in this way have been fully
characterized, but the bar lengths may differ by impractical
amounts. I consider graphs that can be represented using bars all of
equal length. These graphs, called unit-bar visibility graphs
(or UBVGs), have not been fully characterized. I will
discuss results for several classes of graphs, including trees and
outerplanar graphs. The final result is a characterization of the
triangulated polygons (TPs) that are UBVGs. The
characterization uses a character string associated with each TP to
determine if a UBV layout exists and if so, to produce such a
for the final exam. The final exam will emphasize chapter
5. You can find a practice test at:
tests. In fact, this is probably one of the best places
to study for all the chapters, since some multiple choice questions on
the final will be very similar to these. Additional problems may be
taken from (or similar to) these drills:
It is too scary (and probably not even possible) to do every problem
from every drill--just do one from each drill, and note which you are
uncertain about, then go back and do a couple more of that type.
Do this as many times as you have time for.
There will also be a "delta-epsilon" problem, of much the same
flavor as # 15 - 18 in section 2.4, a related rate problem, an
optimization problem, a graphing problem (factored derivatives will be
given), and a proof of the derivative of some like a quotient/product
rule or trig function or its
inverse. These 5 questions will be worth more than the multiple

Screening of �The Proof�
Andrew Wiles announced a proof of Fermat�s Last Theorem, a
conjecture that had fascinated mathematicians for more than 300
years. This video tells the story of Andrew Wiles and his proof.
(This video should be of particular interest to those of you
attending the Hudson River Conference on 4/30 since the invited
address will be about this theorem - and the HRUMC speaker, Ken
Ribet, also appears in this video.)

see the limit is 0.
||The third hour
test will be on Tuesday, April 12. The test will cover sections 3.3-3.8, 3.10, 4.1-4.5. You should study from the tutorial
tests. There will be questions (proofs) for the derivatives
of the trig and inverse trig functions.
Also helpful are the
derivatives, differentiation methods, curve analysis, and mean value theorem tutors
under the tools menu in Maple.
Here are a some drills:
Lhopital drill inf limits,
for inc/dec and questions about f' or f'' pos/neg, and global extremes.
Do not include endpoints for local extremes. Also, on #7 there are
asymptotes at C and E so the function and its derivatives do not exists
there, also skip the 9th one since it has a confusing wrong answer given),

Bacteria Project Revisions:
- Include the names of you partners in
- Include a copy of the original data you were
given by your bio partners.
- If you used the Maplets posted on the
website to determine the parameters, include screen captures in
- Organize information so that it will be easy
for your bio partners to understand:
- Label data sets and plots
- Insert comments above Maple code to
explain what you are doing and why.
- Introduce the answers to the questions in
part 3 so the bio partners will know what you are discussing.
- Edit as though this were an English paper
(in some sense it is�the point of your writing classes is to
develop the skills you need to make reports like this meet
professional standards). Use complete sentences, check grammar
and spelling, etc.
- Analyze all four data sets you were given.
They may not all exhibit logistic growth�that is ok, but you need
to explain why you chose whatever other model you did choose. It
may be that no matter how hard you try with various pairs of data
points and (and values of M for the logistic curve) you still
don�t get a great fit�this is ok as long as you give some
explanation of what might be causing the difficulty.
- If the are questionable data points, ask
your bio partners about it and include the explanation in your

part will be similar, both in content and format, to the first hour
test (multiple choice). You should study from the tutorial
tests. However, there isn't a very large selection there of
problems to practice on (although 3.2 is good)--you should do as many of the
"drill" problems from the inclass demos as possible, since I
am likely to take problems from there for the test as well.
You should be able to compute the slope of the tangent line
(derivative) using the limit definition of the derivative. You
should be able to tell if a function is continuous and if it is
differentiable. You should also be able to sketch a graph of a
function and the tangent line at a point.
There is also an excellent Maple tutor--go to
tools/tutors/calc--single variable/differentiation methods. Do A LOT
of practice with the product and quotient rules!
The second part of the test will ask you to prove at least two of
the differentiation rules--constant multiple, power, sum, product,
quotient, various trig rules.
Here are some good review sources:
Also do the examples in the inclass demos that will generate
different problems for you, for example at the bottom of http://archives.math.utk.edu/visual.calculus/2/definition.8/index.html

Maple printouts--the Maple tutors and assistants, as far as I know,
won't print directly from Maple. If you need a print out of
something you have done on one of them, the quickest way I know is
to press alt/PrtScrn (the PrtScrn button is usually on the
upper right of the keyboard) while the window is up. This
copies the window to the clipboard, and then you can paste it into
another application such as Word, and then print from there.
If you right-click on the image, you can crop it if necessary.
This will work with any active window, not just Maple.

I wish to bring to your attention that once again this year there
will be a conference for undergraduate students interested in
mathematics during the Spring semester. The twelfth annual Hudson
River Undergraduate Mathematics Conference (HRUMC)
will take place on Saturday,
April 30, 2005 at Williams
College in Williamstown, Massachusetts.
The keynote speaker will be Ken Ribet of UC Berkeley. In the past
several years, a contingent of students and faculty from St.
Michael's has gone to the HRUMC, and
several students and faculty members have
given presentations at previous conferences. For more information
about this meeting, you can check out the conference homepage at http://www.skidmore.edu/academics/mcs/hrumc.htm.
At this site, you can find details about last
year's conference which was held at Mount Holyoke College.
At the HRUMC, some talks are given on original research in
mathematics or a related field (done by students, faculty, or
jointly), while others are expositions of interesting work that has
been accomplished and discoveries that have been made in mathematics
(typically not discussed in regular course work). If you think that
you might be interested in giving a talk or attending the conference
to see what it's like, please let me
or anyone else in the mathematics department
know. If you'd like to get more information about this opportunity,
just e-mail me back or stop by my office and I'd be happy to discuss
it more with you. I have copies of recent conference programs if
you'd like to get a feel for what the conference involves and the
type of talks given. I look forward to hearing back from some of you
about this opportunity.
There will be
Help Sessions Mon-Thu 7:30 - 9:00 pm in STE 334, starting date TBA. Note--this
is in St. Eds, and NOT in the hall our class is in.
There will be a trig review--Date TBA

Some of the interactive material in
the Visual Calculus modules uses ActiveMath, which does not work
under Internet explorer. There is a way to see/use the
activemath notebooks. To
start with, you need to be running under Netscape, not Internet
Explorer. If you don't have Netscape, you can down load it for
free here: http://www.netscape.com/download/
(choose the full install when prompted)
You also need the LiveMath Plug-in for
netscape. You can download it free here: http://www.livemath.com/download/
(click on the icon for "Windows for Netscape based
browsers", assuming you are running some version of Windows).
You only need the freeware--you don't have to buy anything!
CAVEAT: This worked for me, but comes with no
guarantees--it may or may not work with the way your computer is
configured. The helpdesk does not in general support netscape--if
you have a problem, you can ask, and they may be able to help you, but
DO NOT hassle them if they can't.
PLEASE, PLEASE: If
you happen to be one of the folks that is able to get this to
work, please, please share your resources with classmates you
may not be able to. Thank you!
