WebbWe claim that the number of needed breaks is n 1. We shall prove this for all positive integers n using strong induction. The basis step n = 1 is clear. In that case we don’t need to break the chocolate at all, we can just eat it. Suppose now that n 2 and assume the assertion is true for all rectangular chocolate bars with fewer than n 4 WebbTogether, these implications prove the statement for all positive integer values of n. (It does not prove the statement for non-integer values of n, or values of n less than 1.) …

It consists of two steps. First, you prove that P(1) is true. This is called the basis of the proof. Then you show: for all n 0, if P(0);P(1);P(2);:::;P(n) are all true, then P(n+1) must be true. olive green stained guitar

Webb15 nov. 2011 · 159. 0. For induction, you have to prove the base case. Then you assume your induction hypothesis, which in this case is 2 n >= n 2. After that you want to prove that it is true for n + 1, i.e. that 2 n+1 >= (n+1) 2. You will use the induction hypothesis in the proof (the assumption that 2 n >= n 2 ). Last edited: Apr 30, 2008.
