Announcements:
- Announced 6/14/2009: Grades are posted here:
https://catalysttools.washington.edu/gradebook/drjenni/5207.
The median on the final exam was a 64. I don't plan on having any office hours
before the beginning of fall quarter, so you'll have to wait until then to
come see your final. Have a great summer and good luck with everything.
- Announced 6/5/2009: Your final exam is next Thursday, June 11, 8:30-10:30 a.m. in our regular classroom. Contrary to what I announced in class today,
I CANNOT hold office hours on Tuesday. My office hours next week will be:
Monday, 12-4, and Wednesday, 10-3.
- Announced 6/5/2009: Here is a list
of results that you may use on the exam.
- Announced 6/3/2009: Here is a Sample Final.
Actually, it's more of a set of review problems. You can expect your final to
be about half as long. But this should be a good indication of the difficulty
of the problems you can expect. I will not be posting solutions. I will
offer hints if you ask for them on specific problems on the discussion board.
I encourage you to get started early on these and to ask a lot of questions.
- Announced 5/25/2009: A reminder that I will be holding office hours
to discuss Wednesday's homework
on Tuesday, 5/26, starting at 5:30 and lasting until everyone leaves or I
get tired of you and kick you out.
- Announced 5/17/2009: For Monday, May 18 only, my office hours will be
2:30 to 4:30 p.m.
- Announced 5/14/2009: We've fallen behind my tentative schedule for
the quarter. I will finish up countability and start on the pigeonhole
principle on Friday, May 15. I will finish the pigeonhole principle and
start talking about divisibility on Monday, May 18. I will continue with
divisibility and talk about the Euclidean Algorithm on Wednesday, May 20.
We'll do a homework Q&A on Friday, May 22. Monday, May 25, is a holiday.
And your next homework is due on Wednesday, May 27. I'll reassess the
schedule then.
- Announced 5/3/2009: I've posted grades. You should be able to view them
by clicking on this link,
logging in to your MyUW account, and clicking on the GradeBook link there.
(Let me know if you have any trouble with that.) If you share a computer,
make sure that you log out and quit your browser after you're done. The median
grade in the course right now is a 3.0.
- Announced 4/26/2009: Please note that I have posted your next TWO homework
assignments on the homework assignments page.
- Announced 4/23/2009: One of your colleagues found a typo in my solutions
to the Sample Exam. On #3, I say: If x is in B but x is not in B intersect C, then x must be in C. Of course, that should be: If x is in B but x is not in B intersect C, then x must not be in C. Thanks for the catch Traci!
- Announced 4/22/2009: Here are the solutions to the old exam.
- Announced 4/16/2009: Your midterm exam will be held Friday, April 24, in class. It will cover all the material we've gone over so far. You should
expect a few short answer problems (like: "Negate the following statement.") and 2 or 3 proofs. You will not be allowed to use any books, notes, or electronic devices during the exam.
Here is the midterm I gave the last time I taught this
course (when it was Math 310). We haven't covered bijections yet, so you
should skip #4. I will post solutions next week.
- Announced 4/12/2009: (Updated 4/13/2009.) For Wednesday, be ready to discuss 2.4 and 2.53. You
only need to bring in copies of 2.53, though. Problem 2.38 is postponed until next week.
- Announced 4/9/2009: A couple of notes about Homework 2. For 2.21, give
a proof of the statement you claim is true. For 2.38, if you say it's true,
give a proof; if you say it's false, give a counterexample.
- Announced 4/3/2009: You'll do your first Group Work session on Wednesday.
Write up a good draft of your proofs for #1.31 and bring in three copies (plus
your own) for critique.
- Announced 4/3/2009: I've created a discussion board for this class. You'll need to log in with your UWNetID and password. Only members of the class will
be able to read your posts, so don't be shy!
- Announced 4/3/2009: I have set my office hours
for the quarter. In addition to these posted hours, I will stay after class
every Wednesday (until 2:15) to answer questions.
- Announced 3/27/2009: Here are a couple of notes about Homework 1:
- Problem 1.41: The wording on this problem is vague. What I'd really like you to do is convince yourself that each of those statements is true. You can demonstrate each for me using a Venn diagram and different kinds of shading.
- Problem 1.50: Depending on which printing of the book you have, this problem may not be stated right. The correct problem is to prove that f(C∩D) &sube f(C) &cap f(D).
