I'm trying to learn coq so please assume I know nothing about it.
If I have a lemma in coq that starts
forall n m:nat, n>=1 -> m>=1 ...
And I want to proceed by induction on n. How do I start the induction at 1? Currently when I use the "induction n." tactic it starts at zero and this makes the base statement false which makes it hard to proceed.
Any hints?
