More clear on epsilon and N | 1 | 02:41, 7 May 2015 |

I would like to see a more stringent calculation that is closer to the definition. Start by defining c as you do, set eps = (c+q)/2 and finish the proof. In fact, this may be second hint!?

So picky - though I think your epsilon choice is wrong (see the new solution)
