What is logical equivalence of statement forms P and Q?
The logical equivalence of statement forms P and Q is denoted by writing P Q. Two statements are called logically equivalent if, and only if, they have logically equivalent forms when identical component statement variables are used to replace identical component statements. 2.1 Logical Equivalence and Truth Tables 4 / 9 Logical Equivalence
Are two logical statements logically equivalent?
Two logical statements are logically equivalent if they always produce the same truth value. Consequently, p ? q is same as saying p ? q is a tautology. Beside distributive and De Morgan’s laws, remember these two equivalences as well; they are very helpful when dealing with implications. p ? q ? ¯ q ? ¯ p and p ? q ? ¯ p ? q.
Is p q a tautology?
Use a truth table to show that [(p ? q) ? r] ? [¯ r ? (¯ p ? ¯ q)] is a tautology. Two logical formulas p and q are logically equivalent, denoted p ? q, (defined in section 2.2) if and only if p ? q is a tautology. We are not saying that p is equal to q. Since p and q represent two different statements, they cannot be the same.
Is p equal to Q?
We are not saying that p is equal to q. Since p and q represent two different statements, they cannot be the same. What we are saying is, they always produce the same truth value, regardless of the truth values of the underlying propositional variables.
