5.1, due February 9th

1. Luckily, this section seemed to be ok, since we've already had these theorems and corollaries in chapter 2. One thing that I don't quite understand why we do, and that I'll have to get used to is the way we denote the congruences classes modulo p(x) on p 122. I don't get why we denote it like that cause to me it looks like we're dividing the function by p(x). Anyway, that's what I don't really understand and am going to have t get used to
2. I really like how this is mostly like chapter 2, except that we're dealing with functions now, but it helps because I've already done stuff like this, so hopefully it won't be too bad.
