Topics in Mathematical Induction

1

Understanding Statements and Notation

  • A statement is a mathematical sentence that is either true or false, but not both.
  • Statements involving natural numbers are often written as \( p(n) \), where \( n \) is a natural number.
  • Examples: \( p(n): 1 + 2 + \dots + n = \frac{n(n+1)}{2} \), \( p(n): 2^n > n \).
2

Principle of Mathematical Induction

  • The principle has two essential steps: the base case and the inductive step.
  • Step 1: Prove \( p(1) \) is true (base case).
  • Step 2: Assume \( p(k) \) is true for some natural number \( k \), then prove \( p(k+1) \) is true (inductive step).
3

Types of Problems Solved by Induction

  • Summation formulas: e.g., sum of first \( n \) natural numbers, squares, cubes.
  • Divisibility statements: e.g., proving \( x^n - y^n \) is divisible by \( x - y \).
  • Inequalities: e.g., \( 2^n > n \), valid for all \( n \in \mathbb{N} \).
