WebOne commonly used (redundant) expressively complete set is {NOT, AND, OR}. Two particularly common canonical sets of expressions over this set are the conjunctive normal form (CNF) and disjunctive normal form (DNF). Both of these are rather verbose. There is also a notion of a minimal expression over a set of connectives, defined variously. WebCase 1: By inductive hypothesis, has an even number of 's and 's in the truth-table. Since all 's become 's and vice versa when negating, that means that has an even number of 's …
