Tautologies Prove that each of the following propositional formulae are tautologies by showing they are equivalent toT (a) ((p !q)^(q !r)) !(p !r)Q ^r)!(p !(q ! Let A = (0, 2q, r), (p, q, r), (p, q, r) If AAT = I3, then p is The correct option is (2) Explanation Since AA T = I so A is orthogonal matrix sum of the squares of the non diagonal elements of one column is ⊥
