Describe the ring $R = \mathbb Z_4[x]/((x^2+1)\mathbb Z_4[x])$ by

  1. listing all the cosets (for example by using coset representatives)
  2. describing the relations that hold between the elements in this ring, that is, describe the relations that hold between these cosets.

    Welcome to math.SE: since you are fairly new, I wanted to let you know a few things about the site. In order to get the best possible answers, it is helpful if you say in what context you encountered the problem, and what your thoughts on it are so far; this will prevent people from telling you things you already know, and help them write their answers at an appropriate level. Also, many find the use of imperative ("Find", "Show") to be rude when asking for help; please consider rewriting your post.2012-03-30

    "Rumbled" is the word which springs to mind. It looks like someone is trying to get help with their homework without obvious effort. At least say how you've tried to solve it and if you have gotten anywhere.2012-04-04
