WebJan 26, 2024 · Lemma1.3: take the induction step (replacing n by 2) and use Lemma1.2when we need to know that the 1-disk puzzle has a solution. It also contains a proof of Lemma1.4: take the induction step (replacing n by 3) and use Lemma1.3 when we need to know that the 2-disk puzzle has a solution. Similarly, all the other lemmas have … Web3 / 7 Directionality in Induction In the inductive step of a proof, you need to prove this statement: If P(k) is true, then P(k+1) is true. Typically, in an inductive proof, you'd start off by assuming that P(k) was true, then would proceed to show that P(k+1) must also be true. In practice, it can be easy to inadvertently get this backwards.
