WebInduction setup variation Here are several variations. First, we might phrase the inductive setup as ‘strong induction’. The di erence from the last proof is in bold. Proof. We will prove this by inducting on n. Base case: Observe that 3 divides 50 1 = 0. Inductive step: Assume that the theorem holds for n k, where k 0. We will prove that ... WebWhat is induction in calculus? In calculus, induction is a method of proving that a statement is true for all values of a variable within a certain range. This is done by showing that the statement is true for the first term in the range, and then using the principle of mathematical induction to show that it is also true for all subsequent terms.
