News & Announcements
07/17 The Finals have been graded. All final grades
are posted on Sakai (including your course
letter grade).
The final exam average was about 70%.
If you would like to look over your exam,
I will be in my office tomorrow morning
around 9:30am-10am and again around 2pm.
Have a great summer!
07/15 I have refreshed all of the grades on Sakai.
Scores for quizzes 1-5, a quiz average (with
lowest score dropped), Maple labs 0, S1, and
S2 scores, and Exam scores are all posted.
07/14 Here is the formula sheet for the final exam.
Here are some review problems (for Chapters 5 & 9).
Dr. Speer provided an excellent set of review problems particularly
pertaining to the material covered since Exam #2. I have edited the
review sheet indicating which problems should be skipped. Also, I have
included a list of sections which you may skip over when studying for
the final exam. We will discuss what the final will cover in class
either Tuesday or Wednesday.
Here is Dr. Speer's review sheet.
07/08 (Curved) scores for Exam #2 are up on Sakai.
The average was 75% (after the curve).
Exam #2 and its answer key can be found here.
07/01 Exam #2 is scheduled for this Thursday (July 4th).
I have posted a formula sheet here.
If you are wondering what to expect on the exam, you
should go here and check out
Exam #2 from my Spring 2007 and Spring 2008 classes.
Dr. Speer posted a nice review sheet for exam #2. You
can find it here.
You can find a Maple worksheet with plots of direction fields in
phase planes for two linear systems of DEs here.
Want some more background in Linear Algebra?
Dr. Speer posted some helpful Linear Algebra Notes.
These help fill in some details left out of your textbook.
In addition, I have taught Math 250 (Intro. to Linear Algebra)
several times. You might find some of the exam problems from
that class helpful. The last 2 times I taught Math 250, I
covered solutions of linear systems of differential equations
as an application of linear algebra (see Exam #2's).
You can find these old exams here.
Exam #1's will have examples of solving linear systems using
Gaussian Elimination. Exam #2's will have Eigenvector/Eigenvalue
problems.
06/22 I *finally* posted the answer key for Exam #1.
You can find it here.
06/19 I reposted grades on Sakai. Hopefully everyone's grades
are listed now. Sakai tried to delete several students.
I think everyone is restored at this point.
06/17 I have posted a "Midterm Guess" on Sakai.
It was computed as follows:
-------------------------------
Quiz #1 + Quiz #2 weighted 20%
Maple 0 + Maple S1 weighted 10%
Exam #1 weighted 70%
-------------------------------
Of course, I do plan on dropping the lowest quiz, so that
component is artificially low. Also, Exam #1 is *very*
heavily weighted (its the only exam I can use for this
estimate), so if you had a "bad day" your average will
necessarily look awful.
Where is Exam #1's answer key? It's coming...soon?
06/15 Exam #1, Maple Lab #0, Maple Lab #S1 grades
have been posted on Sakai.
06/11 Quiz #2 homework problem answers are posted here.
06/10 Quiz #2 grades are posted on Sakai.
Formula Sheet for Exam #1
If you would like an idea about what the exam might be
like, I have posted an old Math 244 exams (with answer
keys) here.
You can find some additional review problems here:
I) Dr. Speer's review problems for Exam #1 (2006).
II) Dr. Speer's review problems for Exam #1 (2007).
06/04 For the homework problem involving Euler's method -- Don't try
to print out all of the intermediate calculations -- There are
too many!!! To suppress output in Maple use ":" instead of ";".
For example:
a := 2; b := 3; a+b;
would print out...
a = 2
b = 3
5
on the other hand,
a := 2; b := 3; a+b:
would print out...
a = 2
b = 3
(2+3=5 is calculated but not printed out)
06/03 Quiz #2 Homework Problems:
--------------------------------------------------
2.3 #23 -- Adapt my Maple example (2.3 #22)
and include appropriate graphs.
8.1 #2 -- You might want to use Maple.
Definitely don't try to do this by hand!
--------------------------------------------------
06/02 I *finally* got the quizzes graded and posted the grades
on Sakai.
05/27 We will have a quiz on Thursday. It will cover Chapter 1
along with sections 2.1, 2.2, and 2.6 (we will cover 2.1
and 2.6 tomorrow).
In addition, Maple Lab #0 is due Monday.

05/26 Everything has been posted. Please be aware that we will have
our first quiz on Thursday and Maple lab #0 is due next Monday.
05/19 Syllabus, schedule, and homework pages will be posted soon.
