Use Fitch to construct formal proofs for the following arguments. In two cases, you may find yourself re-proving an instance of the law of Excluded Middle, P V ¬P , in order to complete your proof. If you've forgotten how to do that, look back at your solution to Exercise 6.33. Alternatively, with the permission of your instructor, you may use Taut Con to justify an instance of Excluded Middle. (P → Q) ↔ (¬P V Q)

Use Fitch to construct formal proofs for the following arguments. In two cases, you may find yourself re-proving an instance of the law of Excluded Middle, PV¬P, in order to complete your proof. If you've forgotten how to do that, look back at your solution to Exercise 6.33 in Language Proof and Logic 2nd Edition. Alternatively, with the permission of your instructor, you may use TAUT Con to justify an instance of Excluded Middle. (P->Q)<->(¬PVQ)

Instructions: For each of the following argument forms, complete a proof of validity, by natural deduction, USING ALL 19 RULES OF INFERENCE. Please note that some of the proofs may allow for alternative sequences of steps. Other than that, there is only one proof possible for each argument form. If a proof is without error, then answer CORRECT, on the CANVAS TEST 4/FINAL page. If there is any error in a proof, then answer THE LINE ON WHICH THE ERROR...
