285L26 Mathematical Induction; Binomial Theorem Mathematical InductionMathematical inductionis a method for proving mathematical statements which involve natural numbers. We denote a statement ( )A n, nis natural. Example: ( )A n: 246...(2 )(1)nn n++++=+, 1, 2, 3,n=…. The Principle of Mathematical Induction:Suppose that the following two conditions are satisfied with regard to a statement ( )A n: 1. ( )A nis true for 0nn=. 2. If ( )A nis true for nk=(0kn≥), it is also true for 1nk=+. Then ( )A nis true for all natural numbers 0nn≥.
