Induction proof of sum of squares
Web2 feb. 2024 · Proof by induction : For all n ∈ N, let P(n) be the proposition : n ∑ i = 1i2 = n(n + 1)(2n + 1) 6 When n = 0, we see from the definition of vacuous sum that: 0 = 0 ∑ i = … Web1 Induction The idea of an inductive proof is as follows: Suppose you want to show that something is true for all positive integers n. (The catch: you have to already know what you want to prove — induction can prove a formula is true, but it won’t produce a formula you haven’t already guessed at.) • Step 0.
