Re: [math-fun] exact and not exact formulas

Hello mr. Gosper, yes, very interesting, explicit formulas : this is what I need. I included your formula for the case k=2/7 on the 3rd version of my preprint here : http://arxiv.org/abs/1101.6066 (tell me if there is an error ?). thanks for all this, très respectueusement, Simon Plouffe
