What exactly is the difference between weak and strong induction?

WebMathematical induction is a proof technique, not unlike direct proof or proof by contradiction or combinatorial proof. 3 In other words, induction is a style of argument we use to convince ourselves and others that a mathematical statement is always true. Many mathematical statements can be proved by simply explaining what they mean. WebJul 6, 2024 · As before, the first step in any induction proof is to prove that the base case holds true. In this case, we will use 2. Since 2 is a prime number (only divisible by itself and 1), we can conclude the base case holds true. 4. State the (strong) inductive hypothesis.

WebAnything you can prove with strong induction can be proved with regular mathematical induction. And vice versa. –Both are equivalent to the well-ordering property. • But strong induction can simplify a proof. • How? –Sometimes P(k) is not enough to prove P(k+1). –But P(1) ∧. . . ∧P(k) is strong enough. 4 WebInduction Hypothesis. The Claim is the statement you want to prove (i.e., ∀n ≥ 0,S n), whereas the Induction Hypothesis is an assumption you make (i.e., ∀0 ≤ k ≤ n,S n), which you use to prove the next statement (i.e., S n+1). The I.H. is an assumption which might or might not be true (but if you do the induction right, the induction
