Let A be a set and let P(A) denote the power set of A. If |P(AxA)| = 16 then |A|=4. - ANSFalse The statement P : for all integers "x", x>0 implies x^2 ≥ 0 is trivially true. - ANSTrue Let a,b,c,d,n be integers. If a+b congruent to c (mod n) and a+d congruent to c (mod n), then b is congruent to d (mod n). - ANSTrue Let n be an integer where n is congruent to 1 mod 4. Then n^12 is congruent to 1 mod 16 - ANSTrue Let P,Q,R be statements. Then Pˇ(QˆR)=(¬(Pˆ¬Q))ˆ(PˇR) -...

Definition of a sequence - ANSA function from N to R epsilon definition of a limit - ANSFor all ε in R>0, there exists N element of R such that for all n element of natural numbers, n > N => |an - L| < ε What does "the limit of an equals L" mean? - ANS"The limit of an equals L" means that when n is large, an is near L. The definition weaves together the largeness and nearness so as to obtain a precise meaning. You tell me ______ . I'll tell you ______. You'll find...
