WebOct 26, 2016 · The inductive step will be a proof by cases because there are two recursive cases in the piecewise function: b is even and b is odd. Prove each separately. The induction hypothesis is that P ( a, b 0) = a b 0. You want to prove that P ( a, b 0 + 1) = a ( b 0 + 1). For the even case, assume b 0 > 1 and b 0 is even. WebApr 4, 2024 · However, a quick and simple proof by (strong) induction shows that it has to be n − 1 breaks for n pieces. Also, you can continue this problem with: Take the same chocolate bar as above, and once again you want to break it into its 28 individual pieces.
