Rapaport" Subject: HW 2 To: CSE191-SP08-LIST@LISTSERV.BUFFALO.EDU | From dsmehta@buffalo.edu Thu Jan 31 16:51:29 2008 | | I had a question for HW#2, for question 50b: (p NOR q) NOR (p NOR q) is logically | equivalent to (p V q). | For above question is it okie if I show Truth Table. By "okie", I assume you meant "OK" :-) The answer is: Yes, that would be a correct way of proving the logical equivalence. But a truth table by itself is not sufficient, as the HW sheet explains. You must also say why the truth table shows that the 2 propositions are equivalent.
