Let U ⊆ R^n be open (not necessarily bounded), let f, g : U → R be continuous, and suppose that |f(x)| ≤ g(x) for all x ∈ U. Show that if exists, then so does . We were unable to transcribe this imageWe were unable to transcribe this image
A metric space (X, d) is totally bounded if, given ε>0, there exists a finite subset = of X, called an ε-net, such that for each x∈X there exists ∈ such that d(x,) < ε. Prove that if Y is a subset of a totally bounded space X then, given ε>0, the subset Y has an ε-net and therefore Y is also totally bounded.

Suppose that f is bounded on a, b and that for any cE (a, b), f is integrable on [c, b (a) Prove that for every e> 0, there exists CE (a, b) so that f(x)(c-a) < € for all x [a,b]. (b) For any > 0, find a partition P of [a, b so that U,P)-J f(r)dz < j and s f(r)dz L(f, P) < Hint: Do this by choosing c carefully and extending a partition of [c, b...
(2) Follow the steps below to prove Theorem 7.2.8: A bounded function / : [a,b] + R is integrable on (a, b) if and only if Ve > 0, there exists a partition P. of (a,b) such that UC, P.) - LIS, P.) <E. (a) Explain why the existence of the partition P. implies that L(I) = (/), and therefore that is integrable. (b) Conversely, ilis integrable, then there exists partitions P, Q of [a,b] such that UU,P) - L(Q)<E...
