How do I apply Commutivity law to a tautology: $P\lor \neg(P \land Q)$?
I understand the it is $A\lor B = B\lor A$, but how can this apply to the above tautology?
Do I assume $P$ as $A$, and $\neg (P\land Q)$ as $B$?
I just checked the answer, the answer is: $\neg Q \lor \top$. Where did the $\top$ come from?
