INTD 301 Problem Sets

Problem Set 1

The first problem set is due February 14. It will contain problems from our work in class during weeks 3 and 4. Problems will be posted here as they arise. They will be finalised on February 8 - in other words I may change the assignment before then (probably not by much, though).

2.8.5, 3.2.13-14 as one problem, write a short explanation for why questions 3.2.18-20 are all very simple - don't show work. 6.4.4, 6.6.9, (read, but don't do, 6.6.10,) 6.6.13, 2.6.8.

Items from our handout of inverse proofs will be added if necessary: Prove the following, in a similar fashion to the way we did in class on 2/2: (-a)(-b) = ab [Be careful not to use (-1)(-1) = 1. This proves that, not the other way around.] Also prove the division algorithm for fractions is true [this is not easy to typeset here, it's #10 on the handout], i.e. (a/b) / (c/d) = ad / bc.

Here are some problems I was considering, but ended up removing because there were too many problems: 3.2.5, 6.3.4
