Scribe Post 10/27/09

At the start of class we had a quiz on the 2.1-2.2 homework. This took us up to 10:05, and from there we began going over some of the more recent homework problems, including pg. 159 (13, 23, 49, 25, 59, and 37). Problem 37 segued nicely into a discussion of the remainder theorem, which as we learned can be used to quickly find specific values of a function such as f(5). Next, we did a review of complex numbers, proceeding with a Venn-diagram of the various types of numbers and the relationships between them. This lead discussion towards terms such as rational, irrational, pure imaginary, etc.; we also reviewed operations involving complex numbers, including a brief discourse on complex conjugates. This took us right up to 10:50, our homework being p. 167/17, 19, 21, 29, 33, 37-51 odd, 65, 71. I haven't gotten a chance to talk to anyone about being the next scribe yet, so I'll do that at the beginning of next class.
