Proof induction

WebSep 5, 2024 · There is another way to organize the inductive steps in proofs like these that works by manipulating entire equalities (rather than just one side or the other of them). Inductive step (alternate): By the inductive hypothesis, we can write ∑k j = 1j = k(k + 1) 2. Adding (k + 1) to both side of this yields ∑k + 1 j = 1j = (k + 1) + k(k + 1) 2. WebMar 18, 2014 · Mathematical induction is a method of mathematical proof typically used to establish a given statement for all natural numbers. It is done in two steps. The first step, known as the base case, is to prove the given statement for the first natural number. The second step, known as the inductive step, is to prove that the given statement for any ...

Typically, in an inductive proof, you'd start off by assuming that P(k) was true, then would proceed to show that P(k+1) must also be true. In practice, it can be easy to inadvertently get this backwards.

This modified induction is known as the strong form of mathematical induction. In contrast, we call the ordinary mathematical induction the weak form of induction. The proof still has a minor glitch!

WebThis shows that P(n + 1) is true and finishes the proof by induction. The two sets are disjoint if n + 1 = 2. In fact, the implication that P(1) implies P(2) is false. As you can see, induction used improperly can prove ridiculous things. Often times the mistakes are subtle. It takes a good understanding of induction to use it correctly.
