WebA Tautology is a formula which is always true for every value of its propositional variables. Example − Prove [ ( A → B) ∧ A] → B is a tautology The truth table is as follows − As we can see every value of [ ( A → B) ∧ A] → B is "True", it is a tautology. Contradictions WebJan 19, 2024 · The nature of variables within proofs. I am confused about how best to view certain kinds of variables that show up in the course of an elementary proof. For example, to prove that the square of every odd integer is odd, I would write: Let m ∈ Z be arbitrary. Suppose m is odd. Choose k ∈ Z such that m = 2 k + 1. Then m 2 = ( 2 k + 1) 2 …
