 books.google.com If two sentences are logically equivalent, the truth value of one is always the
same as the truth value of the other. This means that their corresponding
biconditional will always be true. It is a tautology. For this reason, logically
equivalent ...

 books.google.com The logical forms of S1 and S2 can be expressed as ∀xPx → Q and Q ∨ ∃x∼
Px respectively. Since this is (an instance of) logical equivalence fin Example 3
above, S1 and S2 are logically equivalent by clause 2.1 of Procedure LEQ. 

 books.google.com A logically compound sentence in standard notation has one, and only one, main
connective, and each embedded sentence in turn has, at most, one main
connective. As a result, the natural deduction proof of the equivalence of, say, 'P
