comment $p$-adic numbers and projective coordinates
Right, thanks. I added that. We take $(0:1:0)$ to be the group identity in all groups considered.

comment Cassel's book on Elliptic Curves
@Lubin Sorry, I would not. I would like to avoid any fancy proofs. Cassels' says that this theorem follows by induction, using the lemma that proceeds it (as stated in the question). My question is: how does it follow by induction? He says it like it's obvious, so I'd like to know what he's thinking. Then again, he leaves out lots of steps all over the book.
