![]() ![]() In the general case, the proof of x with 2 n variables will have height 2 n, because every extra variable will require one extra inference above everything else. The proof of y will have a symmetrical shape, but the proof of x will appear triangular, with more inference on the right side than on the left. Since P → Q and ¬Q → ¬P are WFFs, ( P → Q) ↔ ( ¬Q → ¬P ) is a WFF.ġ1.Since P, Q, ¬Q, and ¬P are WFFs, P → Q and ¬Q → ¬P are WFFs.Rosen 2008 Elements Of Discrete Mathematics 2/E-C L Liu Discrete Mathematics-Oscar Levin Note: This is the 3rd edition. Since P → Q and ¬P → Q are WFFs, ( P → Q) ( ¬P → Q) is a WFF. Discrete Mathematics and Its Applications-Kenneth H.Since P → Q and P → ¬Q are WFFs, ( P → Q) ( P → ¬Q) is a WFF.Previous editions of the book have been used successfully by students at hundreds of institutions in North and South America, Europe, the Middle East, Asia, and Australia. ![]() #Discrete math epp pdf pdf
