Revision as of 12:15, 19 October 2008 by Nmisner (Talk)

Hey everyone! I'm sure no one will see this but I'm hoping someone will. I'm having a lot of trouble in the class and wondering if there is anyone that could help me. I seem to understand everything in class and most of the homework...but that exam really showed me how much I don't know. Just talk to me in class if you think you could help me!

Thanks! Neely


I am really confused on the whole left and right cosets idea. When we did the following example

G = 6 mod 6Z H = {0,2,4}

Question 1: Did we use 0-5 because they were the elements of 6 mod 6Z? This would make sense to me if that's the case.

So then we found that when adding H to 0, 2, and 4 the result was H. So are these the only cosets or are 1, 3, and 5 a coset as well? Are they considered left cosets if they are a coset?

Hopefully someone sees this and responds to me before I do the next homework!!!
