NOTES ON SUP’S, INF’S AND SEQUENCES LANCE D. DRAGER The purpose of these notes is to brie y review some material on sup’s, inf’s and sequences from undergraduate real analysis, to give an introduction to using these... Find inf S4 and supS4. Since 1/2 ≤ 1 − (−1) n /n ≤ 2, the set S 4 has a lower bound 1/2 and an upper bound 2, and by the Completeness Property has an inﬁmum and supremum.

bounded from below by infAf, so infAg ≥ infAf. Note that f ≤ g does not imply that sup A f ≤ inf g; to get that conclusion, we need to know that f(x) ≤ g(y) for all x,y ∈ A and use Proposition 2.10.... When trying to find lim sup and lim inf for a given sequence, it is best to find the first few A j 's or B j 's, respectively, and then to determine the limit of those.
