Math 1120 (Sections 101 & 102) Homepage
News & Announcements
12/16 Final grades have been posted on asULearn.
If you would like to look over your exam, please
stop by my office this spring (or send me an
email to arrange a time).
Have a great Christmas break!
12/10 Due to the very nasty weather forecast:
Monday's exams will be held on Wednesday.
Here are your options:
You can take the exam either on Tuesday or Wednesday.
Both exams will be held from 12pm until 2:30pm in our regular
classroom (Walker 106).
I counted the seats and there are enough for *everyone* to
take the exam on Tuesday (it would just be a bit crowded).
You don't need to let me know when you plan on taking the
exam. I'll be prepared with enough copies for whoever shows up.
FINAL: Math 1120 Final Exam (Sections 101 and 102):
TIME: 12:00pm until 2:30pm
ROOM: Walker 106 (regular classroom)
DATE(S): Tuesday or Wednesday December 14 or 15.
See you Tuesday or Wednesday!
12/06 Monday afternoon office hours canceled.
Well, it wouldn't be Appalachian without some really
cold weather and canceled classes. Sorry our last day
of review was canceled.
If you would like to pick up your quiz #8, homework #3,
or test #3 corrections, I will do my best to get to my
office this morning for regular office hours.
Office hours this week:
Monday 10am - 12pm & 2pm - 4pm
Tuesday 10am - 12pm
Wednesday 10am - 12pm
Thursday 10am - 12pm
Friday 10am - 12pm
I will probably be in my office before 10am every day.
Feel free to call to see if I'm already there. Also,
if the weather looks really bad, calling ahead to see
if I made it in would be a good idea.
12/04 Test #3 Corrections finished -- grades posted.
I computed new Test #3 grades as follows:
Old Test Score + (Test Corrections - Old Test Score)/2
So I gave back half of the improvement in your grade.
[A few people also got a bonus point or two for
various reasons.]
Final Exam Review Sheet
All of our tests are now posted (with answer keys) as
well as Spring 2009's tests and final exam (with keys):
Old Exams
Homework Set #3 and Answer Key (.mw)
All scores (quizzes, homeworks, and tests) have been
re-posted to AsULearn.
Please look over the recorded grades and let me know
if you notice a mistake. The final quiz/homework
average was computed (in Excel) as follows:
=SUM(F2:P2)-MIN(F2:M2)-SMALL(F2:M2,2)-MIN(N2:P2)+IF(MIN(N2:P2)/2>SMALL(F2:M2,3),MIN(N2:P2)/2-SMALL(F2:M2,3))
(Quizzes were located in cells F2 -- M2 and homeworks in N2 -- P2)
This means I added all of the scores together and then
dropped the lowest 2 quiz scores and the lowest homework
score. In addition, if the lowest homework score divided
by 2 was bigger than the 3rd lowest quiz score, I then
removed the 3rd lowest quiz and put in half of the
lowest homework score [remember homeworks were out of
20 and quizzes out of 10, so homeworks have to be
scaled by 1/2 to match quizzes].
In the end 60 points came from 6 quizzes and 40 points
came from 2 homeworks. This adds up to 100 points and
will be used as your Quiz/Homework average when computing
final grades. Next, time I'll try to make it a little
more complicated :)
11/16 Homework Set #3 due Tuesday, November 30th.
As I have mentioned in class, I will be dropping
the lowest of your 3 homework grades. So if you
like your scores on homeworks 1 and 2, you may
skip this one. Also, for those who do all 3 assignments
I will consider using the lowest score as a
replacement quiz score or something.
To help you get started, here are some examples
of computing with improper integrals and sums in Maple...

11/15 Test #3 scores are posted on AsULearn. Same as with
the last test. Rework you test and turn in corrections
(by Tuesday next week) and you can get up to half of
your points back. This time I will take into account
how much your work improved from the original test
and corrected test when determining how many points
to give back. As before...
---> YOU MUST TURN IN YOUR ORIGINAL EXAM WITH YOUR CORRECTIONS!!!
Note: To avoid a certain unintended technical detail,
change the lower bound on problem 4 part a from x=0 to x=1.
If you leave it as x=0, then when comparing you'll end up
comparing to a p-series which converges on [1,infinity]
but diverges on [0,infinity]. If for some reason you want
to keep the original problem, simply break up the integral
into two pieces one from 0 to 1 and one from 1 to infinity.
A comparison test will show 1 to infinity converges and the
integral from 0 to 1 converges because it's proper (no bad
spots).

11/10 Homework #2 answer key.
11/09 Here is a quick review of test #3 material along with the formulas
I will give you on tomorrow's test: Test #3 Review
Here are some extra convergent/divergent integral problems:

Test #3 from Spring 2009 should be helpful:
Old Tests
11/07 Test Answer Keys have been posted.
I posted grades on AsULearn. If anything on AsULearn doesn't match
the grade you think you have, please let me know.
10/25 We will meet in Walker 205 (the Mac Lab) on Thursday, October 28th
to go over questions about homework #2.
10/22 Homework Set #2 is due Tuesday, November 2nd.
To help you get started, here is a demo of how
to compute Taylor and Fourier polynomials in
Maple...Taylor and Fourier Demo (.mws)

Also, here is the answer key for Spring 2009's
homework #2.
Feel free to modify these worksheets to help
with your homework.
10/20 Test #2 (.pdf) posted.
I will hand back tests today. Please redo your
exam. Write up a neat set of solutions. Staple
your solutions to your original test and turn
it in by Thursday after the break. I will give up
to 1/2 of your missed points back. So a 60 (with
perfect corrections) could turn into 60 + 40(1/2) = 80.
---> YOU MUST TURN IN YOUR ORIGINAL EXAM WITH YOUR CORRECTIONS!!!
10/04 Homework #1 (.pdf) and Answer Key.
09/24 As promised, here is the Extended Example (.mw) from yesterday.
I added a lot of comments and included a computation of error
bounds for midpoint, trapezoid, and Simpson's rules.
09/23 Examples from Today (.mw) --- This hasn't been edited yet.
I will (hopefully) add in trapezoid and simpsons error bound examples
sometime before lunch tomorrow.
