WebA stronger statement (sometimes called “strong induction”) that is sometimes easier to work with is this: Let S(n) be any statement about a natural number n. To show using strong induction that S(n) is true for all n ≥ 0 we must do this: If we assume that S(m) is true for all 0 ≤ m < k then we can show that S(k) is also true.

WebSolution: We will prove by strong induction the statement P n: all f(a) = a for a < n, and the n-th smallest value in the set ff(i)gis uniquely f(n). That is, the unique index which attains that mark is i = n. For n = 0, there is nothing to prove. For n = 1, consider the smallest value, and suppose it is attained (possibly not uniquely) by f(a). current time in hannover germanyWebabn: to make the induction work Thus we need to solve abn 1 + abn 2 abn: or b2 b 1 0 : By the quadratic formuls, we get b ( 1) p ( 1)2 4 1 1 2 1 = 1 5 2 Only the positive value can hold.
