- PS11 will be graded and available for pickup at my Math 19
finals review session, Fri Dec 10, 2:30, in
**MacQuarrie Hall 324**. Just come in, no need to knock or be shy. - Review for final exam, Mon Dec 13, 12:15,
**MacQuarrie Hall 322**. This will also be the last chance to revise PS09-11, and answers to PS09-11 will be handed out at this time. -
**Final exam, Thu Dec 16, 9:45am-noon, in our usual room.** - If you'd like to do some review/self-study on methods of proof, see this handout on writing proofs. You might also try looking at Reading, Writing, and Proving, by Daepp and Gorkin.

Course content: Axioms for groups and rings,
Cayley tables for D_{6}.

Patterns for: D_{4} calculators
(squares), D_{5} calculators
(pentagons), D_{6} calculators

Proof handout: Parts I-II.

- If you're interested in typesetting math, the system I use to
make my handouts is called LaTeX. If you have a Windows PC, you can
download LaTeX for free at http://www.miktex.org; you will also
need a good text editor, like the shareware program WinEdt. PCTeX also makes a good commercial
version; student prices are $150 for the "Publisher" version, which I
recommend if you have the money, $50 for the "Writer" version, which I
recommend if you don't. If you own a Mac, you can download a complete
system called TeXShop for free.
If you own a Linux computer, you already own a copy of this program,
as it's been a standard Unix program for about 20 years.
LaTeX is well worth learning, if you have some free time; it's used for manuals and technical reports throughout nerd-dom. For self-study, I highly recommend Learning LaTeX (Griffiths and Higham) for beginners, and the LaTeX book by Leslie Lamport as a reference.
