WebInductive Step : Prove the next step based on the induction hypothesis. (i. Show that Induction hypothesis P(k) implies P(k+1)) Weak Induction, Strong Induction. This part was not covered in the lecture explicitly. However, it is always a good idea to keep this in mind regarding the differences between weak induction and strong induction. WebRewritten proof: By strong induction on n. Let P ( n) be the statement " n has a base- b representation." (Compare this to P ( n) in the successful proof above). We will prove P ( 0) and P ( n) assuming P ( k) for all k < n. To prove P ( 0), we must show that for all k with k ≤ 0, that k has a base b representation. WebA proof of the basis, specifying what P(1) is and how you’re proving it. (Also note any additional basis statements you choose to prove directly, like P(2), P(3), and so forth.)
