For each of the following give a concrete definition using quantifier expressions and simplifying the negations as much as possible, specifying what you need to prove to show. (a) Given integers a, b, n, that a is not congruent to b modulo n. (b) Given a sequence In, and a real number L, that the sequence On does not converge to L. (c) Given integers a, b that a does not divide 6 (d) Given a function f : X - Y that f is not injective. (e) Given a function f : X – Y that f is not surjective.
