6. Give an example of a non-constant sequence that satisfies the given conditions or explain why such a sequence does not exist: (1) {an} is bounded above but not convergent. (2) {an} is neither decreasing nor increasing but still converges. (3) {an} is bounded but divergent. (4) {an} is unbounded but convergent. (5) {an} is increasing and converges to 2.
6. True or False. If the statement is true, explain why using theorems/tests from class, and if the statement is false provide a counter example. (a) If an and are series with positive terms such that is divergent and an <by for all r, then an is divergent. I (b) If a, and be are series with positive terms such that is convergent and an <br for all 17, then an is convergent. (e) If lim 0+1 = 1 then...
Problem 1: Determine whether the statement is true or false. If the statement is true, then prove it. Otherwise, provide a counterexample. (a) If a continuous function f:R +R is bounded, then f'(2) exists for all x. (b) Suppose f.g are two functions on an interval (a, b). If both f + g and f - g are differentiable on (a, b), then both f and g are differentiable on (a,b). Problem 2: Define functions f,g: RR by: x sin(-),...
1. Answer True or False, and give a brief justification for each answer: a) If lim 2 = 5 then the series i converges to 5. b) If = 5 then lime = 5. c) If S. and lim.- S.-5, then 10 -5. d) The series 5-5+5-5+... is divergent. e) If = 0 = 5 and the = 5, then 20 - 5 f) The Divergence Test can be used to prove a series is convergent.
If a statement is true, prove it. If not, give an example of why it is false. Please neatly and carefully show all necessary work. u. JUULEGADU V W le CLLIULIA LIIV LIVES CASUAL .U . 7. If PLY f(x,y) = if (x, y) + (0,0) if (x, y) = (0,0), then fr(0,0) = 1 and f,(0,0) = 0. 8. If fe and fy are both bounded in an open ball about (a,b), then f is continuous at (a,b).
(3 points each) Determine whether each statement below is True or False. Give a counter-example for each false statement. (a) Every abelian group is cyclic. (b) Any two finite groups of the same order are isomorphic. (c) A permutation can be uniquely expressed as a product of transpositions. (d) Any ring with a unity must be commutative.

Determine whether the statement is TRUE or FALSE. You are NOT required to justify your answers. (a) Suppose both f and g are continuous on (a, b) with f > 9. If Sf()dx = Sº g(x)dx, then f(x) = g(x) for all 3 € [a, b]. (b) If f is an infinitely differentiable function on R with f(n)(0) = 0 for all n = 0,1,2,..., then f(x) = 0 for all I ER. (c) f is improperly integrable on (a,...
