Logical Equivalences Compound propositions that have the same truth values in all possible cases are called logically equivalent. We can also define this notion as follows. DEFINITION 2 The compound propositions p and q are called logically equivalent if ↔ is a tautology. The notation p ≡ q denotes that p and q are logically equivalent.

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

But t is not a tautology, and hence the Modus Ponens is not a logical equivalence. 2. Solution 13: Let. BG: there was a ball game,.

Remark: The symbol ≡ is not a logical connective, and p ≡ q is not a compound proposition but rather is the statement that p ↔ q is a tautology. The symbol⇔is sometimes used instead of ≡ to denote logical equivalence. One way to determine whether two compound propositions are equivalent is to use a truth table.
