Today:
- Announcements
- Homework 2.6 returned: #10, 13, 26.
- #10: showing each step in the process would be nice...
- #13: Most of you got the recurrence relation right, and
figure out that the answers are triangular numbers.
- #26: Many of you didn't notice that there was a
restriction on $m$. That was part of the problem! You were a
little too terse, as a rule.
- Project moment: I've always been interested in improved Venn
diagrams, or the Logic of Lewis Carroll. Either of these would
be interesting to me....
- Today we really begin with section 5.1: Graphs and Their Representations
