Mathematical induction wrong
Mistake: I.H.: Assume that Sk is true for all k ≤ n. Inductive Step: We want to prove Sk+1. What is k? Where has n disappeared? The induction hypothesis is ... ,Inductive Step: For k=n+1 is k=a+b for two natural numbers a,b≤n. It is 2(n+1)=2a+2b=0+0=0. This seems to be a variant of the alternative inductive step ...,Claim: ddxxn=0 for all n≥0. Base case: (n=0): ddxx0=ddx1=0. Inductive step: Assume that ddxxk=0 for all k≤n. Then by the product rule,.,We start by listing several flawed induction proofs. You should work through them and figure out what went wrong. You can jump to the end to see rebuttals ... ,Then maxr−1,s−1}=n. By the inductive hypothesis, r−1=s−1 and hence r=s. Thus P(n+1) is true. The result is now proved by mathematical induction. Share. ,To help you feel more confident about induction, let's try to prove a couple of statements that we know are wrong, so you can see that you can't use ... ,Below are some examples of false induction proofs that illustrate what can happen when some minor details are left out. In each case, the statement claimed ... ,Conclusion: By the principle of induction, (∗) holds for all n ∈ N. Where the error lies: Here there is no problem with the induction step, but the base case ...
