Mathematical Induction
- Mathematical induction is a method to prove statements dependent on a variable n.
- The technique involves two main steps:
- Base Case: Verify the statement for n=1, ensuring P(1) is true.
- Inductive Step: Assume the statement is true for n=k (P(k) is true), and prove it for n=k+1 (P(k + 1) is true).
Example Proof of Summation
- Objective: Prove the formula for the sum of the first n natural numbers:
- (\sum_{i=1}^{n} i = \frac{n(n + 1)}{2})
- Base Case: For n=1, the left-hand side equals 1 and the right-hand side equals (\frac{1(2)}{2} = 1), confirming P(1) is true.
- Inductive Step:
- Assume for n=k: (S_k = \frac{k(k + 1)}{2})
- Show for n=k+1: (S_{k+1} = S_k + (k + 1))
- Thus, (S_{k+1} = \frac{k(k + 1)}{2} + (k + 1) = \frac{(k + 1)(k + 2)}{2}), proving P(k+1) is true.
