Understand the difference between the two forms of induction. Let F be the class of integers for which equation 1 holds. Show that given any positive integer n n n3 2n n 3 2 n yields an answer divisible by 3 3.
Here is a more reasonable use of mathematical induction.
It explains how to use mathematical induction to prove if an alge. It has only 2 steps. Show it is true for the first one. De Moivres theorem states that coso isinon cos no isin no.
