Question
Q(A). Let {fn(=)}
defined over [2,3]. Show that
(a) fn(x) is meaurable and monotonic increasing for all n.
(b) {Sn(z}} converges a e. to a function f(x) to be determined
n=1 = {1+(z-2)" J
be a sequence of functions
(c) Apply the monotone convergence theorem to evaluate Lim fn(z)dµ.
(B) Let {fa(z)} = {rlnz.cos(z-1)"},
be a sequence of meaurable functions defined over [1,2]. Show that:
(a) {Sn(z)} converges to a function f(x) to be determined.
(b) Show that fa(z) is dominated by some integrable function for all n.
Then apply the dominated convergence theorem
100
to evaluate Lim z In z.cos(z – 1)"du.
