WebAug 16, 2024 · There are two basic methods for proving P ⇒ C: Directly: Assume P is true and prove C is true. Indirectly (or by contradiction): Assume P is true and C is false and prove that this leads to a contradiction of some premise, theorem, or basic truth. The method of proof for “If and only if” theorems is found in the law (P ↔ C) ⇔ ((P → C) ∧ … WebContradiction is a more powerful proof method than contraposition, because we're not limited to proving universal conditional statements. The methods of contradiction and …
