Web4 CS 441 Discrete mathematics for CS M. Hauskrecht Mathematical induction Example: Prove n3 - n is divisible by 3 for all positive integers. • P(n): n3 - n is divisible by 3 Basis Step: P(1): 13 - 1 = 0 is divisible by 3 (obvious) Inductive Step: If P(n) is true then P(n+1) is true for each positive integer. • Suppose P(n): n3 - n is divisible by 3 is true. WebSTEP 1: We first show that p (1) is true. Left Side = 12= 1 Right Side = 1 (1 + 1) (2*1 + 1)/ 6 = 1 Both sides of the statement are equal hence p (1) is true. STEP 2: We now assume …

[thm5]The Division Algorithm If a and b are integers such that b > 0, then there exist unique integers q and r such that a = bq + r where 0 ≤ r < b. Consider the set A = {a − bk ≥ 0 ∣ k ∈ Z}. Note that A is nonempty since for k < a / b, a − bk > 0. fathom submissions
