Strong Induction or Complete Induction Proof of Part 2: (uniqueness of the prime factorization of a positive integer). Suppose by contradiction that ncan be written as a product of primes in two di erent ways, say n= p 1p 2:::p s and n= q 1q 2:::q t, where each p i and q j are primes such that p 1 p 2 p s and q 1 q 2 q t. When we remove all common primes from the two factorizations, we have: p... Proof by Induction: Induction is used to prove a statement holds for all natural numbers bigger than or equal to a given natural number a (which will often be 0 or 1).

Strong Mathematical Induction Example Proof (continued). Now, suppose that P(k 3);P(k 2);P(k 1), and P(k) have all been proved. This means that P(k 3) is true, so we know that k 3 = 4a+5b for some integers a and b. Adding 4 to both sides we have k 3 + 4 = 4a + 5b + 4 k + 1 = 4(a + 1) + 5b so P(k + 1) must be true, completing the induction. MAT230 (Discrete Math) Mathematical Induction Fall... Induction, Graphs and Trees 4.1 Mathematical Induction Smallest Counter-Examples We’ve seen one way of proving statements about inﬁnite universes, namely consider a “generic” member of the universe and try to derive the desired statement about that generic member. When our universe is the universe of integers, or is in a one-to-one correspondence with the integers, there is a second

- Proofs by mathematical induction are, in fact, examples of deductive reasoning. History. In 370 BC, Plato's Parmenides may have contained an early example of an implicit inductive proof. The earliest implicit traces of mathematical induction may be found in Euclid's proof that the number

- Yue Kwok Choy. Question. Prove, by Mathematical Induction, that. is true for all natural numbers n. Discussion. Some readers may find it difficult to write the L.H.S. in P(k + 1).
- Complete induction is equivalent to ordinary mathematical induction as described above, in the sense that a proof by one method can be transformed into a proof by the other. Suppose there is a proof of P ( n ) by complete induction.
