Welcome to math.SE: since you are 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; this will prevent people from telling you things you already know, and help them give their answers at the right level. If this is homework, please add the [homework] tag; people will still help, so don't worry. Also, many find the use of imperative (Prove, Find, etc.) to be rude when asking for help; please consider rewriting your post. –  Did Nov 1 '12 at 13:22

So you replaced find by how do we find. Good. But this does not address the main concern, which is that you merely COPIED the text of an exercise (probably homework) without showing ANYTHING about what you tried to solve it. –  Did Nov 1 '12 at 15:56
