How many base cases for strong induction
Web1. Is induction circular? • Aren’t we assuming what we are trying to prove? • If we assume the result, can’t we prove anything at all? 2. Does induction ever lead to false results? 3. Can we change the base case? 4. Why do we need induction? 5. Is proof by induction finite? • Don’t we need infinitely many steps to establish P(n) for ... WebBefore discussing strong mathematical induction formally we will state that the three cases we did rst are the three base cases and that the thing we notice is the inductive step. Observe that all three base cases were necessary because we can’t try to do 20¢by doing 17¢and adding a 3¢stamp because we haven’t done 17¢, and in

WebJan 28, 2014 · Strong induction is often used where there is a recurrence relation, i.e. a n = a n − 1 − a n − 2. In this situation, since 2 different steps are needed to work with the given formula, you need to have at least 2 base cases to avoid any holes in your proof. WebQuestion 1. Determine if each of the following conjectures could be proven with weak induction or if you would need strong induction and explain your reasoning. Also, tell how many base cases would need to be proven. Note: You do not have to actually prove them! (a) Let \ ( T (N)=T (N-1)+3 \) and \ ( T (1)=1 \).
WebYour inductive step needs to build off of your base case (s). If your base case was just P (12) then you would have to show that you can make 13 cents in stamps from 12 cents in stamps and 4 and 5 cent stamps. If you can make n cents, if you add a 5 cent stamp and remove a 4 cent stamp to make n + 1.
Webmethod is called “strong” induction. A proof by strong induction looks like this: Proof: We will show P(n) is true for all n, using induction on n.

Only a = b = 1satisfies this condition. Inductive Case: Assume A(n)for n >= 1, and show that A(n+1). If max(a, b) = n+1, then max(a-1, b-1)= n. By the inductive hypothesis, a-1 = b-1, so a = b. •Corrollary: 3 = 5 •Proof: max(3, 5) = 5. lighting for web meetingsWebNotice that we needed to directly prove four base cases, since we needed to reach back four integers in our inductive step.
