Simple induction proofs
WebbMathematical induction is a method for proving that a statement () is true for every natural number, that is, that the infinitely many cases (), (), (), (), … all hold. Informal metaphors help to explain this technique, such as … WebbA proof by induction consists of two cases. The first, the base case, proves the statement for = without assuming any knowledge of other cases. The second case, the induction step, proves that if the statement holds for …

WebbIn Coq, the steps are the same: we begin with the goal of proving P(n) for all n and break it down (by applying the induction tactic) into two separate subgoals: one where we must show P(O) and another where we must show P(n') → P(S n'). Here's how this works for the theorem at hand: Theorem plus_n_O : ∀n: nat, n = n + 0. Proof. Webbinductive hypothesis: We have already established that the formula holds for n = 1, so we will assume that the formula holds for some integer n ≥ 2. We want to verify the formula …
Webbwith induction and the method of exhaustion is that you start with a guess, and to prove your guess you do in nitely many iterations which follows from earlier steps.
