Final exam stats: n=45; min=5; 1st quartile=26; median=33; 3rd quartile=40; max=59
Note: I dropped everyones lowest final exam problem, so the maximum score possible was 60 points.
I will be working on course grades. I will email everyone when they are available.

This is a page of references that will be part of your final exam. Let me know if there is anything else you would like to see on this.

Here is a course summary.
Here are some practice problems.

Here is a pdf on generating functions, written by Herbert Wilf. It is very well written, and easy to read. I recommend reading pages 1 through 9 for now (this will be all you'll need for this course).

Stats for the third homework: n=47; 1st quartile=5; median=9; 3rd quartile=15; max=18
Here is a histogram of the scores from the third homework:
The large number of zeros is due to students not turning in the assignment. I did not grade anyone to zero (everyone who turned anything in got more than zero points). Why did so many people not turn in the assignment? I don't know.
Here is a histogram of everybody's overall percentages after the third homework. Notice that it is more spread out than the previous overall histogram posted after the midterm. Also, a few people have dropped, so some of the extreme lows are now gone. As last time, I didn't drop any of the homeworks for this calculation, though I will when I actually do grades (and for some later histograms).

Answers to the midterm exam can now be found in the exam archive.

Here is a histogram of everyone's overall percentages (calculated by treating the midterm score as the entire exam portion of your grade, and the two homeworks covering the entire homework portion (with no drop, since we've only had two!)).

Here are the stats for the second homework: n=40; min=4; 1st quartile=7; median=8.5; 3rd quartile=11; max=12 (7 students).
Eight people didn't turn in any of this assignment. I didn't include them in the stats above, but they are in the histogram below.

We meet today, and every Thursday preceding a Friday when homework is due from 5 to 7 in Padelford C-401.

I made a small change to homework 2, problem 6: I clarified that the p values are the primes in the prime factorization of n.
April 15, 2014
Here is a short handout on bases, that might be helpful for homework 2 if you have never seen this sort of thing before.
Here is a set of review problems for the midterm. Work on these over the weekend, and we can discuss them in class on Monday.

I wrote some incorrect bits in today's lecture. Please read this and correct your notes, and ask me any questions that might arise.
April 9, 2014
Here is an online tool for factoring (large) integers. Feel free to use it any time.
April 7, 2014
A reminder: we meet Thursday, from 5 to 7 PM, in Padelford C-401 to discuss homework. Ideally, come with problems worked on so the discussion will help you the most. But you should show up whether you've tried the problems or not.
April 6, 2014
You should work problems 2 through 7, at the end of section 2.1, for practice. Answers are at the back of the book.

New stuff:
- Extra examples pdf with extra material, proofs, etc., that may be of interest.
- GCD Grid explorer An applet I wrote to investigate the grid of relative primality. Have fun!

For Wednesday, please
- Get the textbook.
- Read the first chapter (pages 1 to 15).
- Read the homework guidelines pdf (link at right).

Welcome to Math 301 A, Spring Quarter 2014.
The course discussion board is now availble (link at right). Please take advantage of it to ask questions about homework problems or course topics. You might also use it as a way to arrange study groups. I will get immediate emails when posts are added to the board, so this is as good a way to contact me as email, but allows everyone to see my response.
For those students looking for an add code, I do not overload my courses. As long as you wish to add the course, you should attend every day. If there are openings on Monday of the second week of class, be sure to speak to me; I will make sure that those spaces are filled. Monday of the second week of class will be the last day that I will allow adds to the course.
Be sure to read the Homework Guidelines pdf before you start thinking about writing up the first homework assignment.
