WebbMathematical induction can be used to prove that an identity is valid for all integers n ≥ 1. Here is a typical example of such an identity: 1 + 2 + 3 + ⋯ + n = n(n + 1) 2. More generally, we can use mathematical induction to prove that a propositional function P(n) is true for all integers n ≥ a. Principal of Mathematical Induction (PMI) Webb24 mars 2024 · Surjection.
