+00 bn are series with positive terms an and (a) Suppose that O bn is convergent. Prove that if "limo and that I1 n= 1 +00 then Σ an is also convergent. (b) Use part (a) to show that the series converges t In (n) +00 bn are series with positive terms an and (a) Suppose that O bn is convergent. Prove that if "limo and that I1 n= 1 +00 then Σ an is also convergent. (b) Use part...
(66) (a) Define: A series of real numbers, Enzo an. (b) Define: A real series ,n=o An converges. (c) Define : A geometric series. (d) Derive the formula for the sum of a convergent geometric series.
(4) Given that and are both convergent series of positive terms, prove that is also convergent.

Let (an) be a sequence of strictly positive real numbers and Sn = ak (a) Suppose that the series Σ an/ S,. an is convergent, determine the nature of the series an is divergent, show that 00 (b) Suppose that the series 1 1 Sn-1 Sp an a/S Then deduce the nature of the series 41. Let (an) be a sequence of strictly positive real numbers and Sn = ak (a) Suppose that the series Σ an/ S,. an...
PROVE OR DISPROVE 1. If {an} is a non-increasing sequence of positive real numbers such that Σ" an converges, then lim na 0
3) Let (an)2- be a sequence of real numbers such that lim inf lanl 0. Prove that there exists a subsequence (mi)2-1 such that Σ . an, converges に1
Is the following series convergent or divergent? If it is convergent, then evaluate what the series converges to. noor(n+1)ī (sin?(x)) Zn=1Jnt I dx
Prove that the function f(x)= 1/(1-x) is real analytic (i.e. it can be represented as a convergent power series) on the interval (w, 1) for every w < 1 and the interval (1, w) for every w 1 Prove that the function f(x)= 1/(1-x) is real analytic (i.e. it can be represented as a convergent power series) on the interval (w, 1) for every w
real analysis Find the limit of the sequence as n to or indicate that it does not converge en2 0 (0,0,1) O Does not converge 0 (0, 1, 7) 0 (0,0,0) Is it true that any unbounded sequence in RN cannot have a convergent subsequence? Please, read the possible answers carefully. 0 Yes, because any sequence in RN is a sequence of vectors, and convergence for vectors is not defined. o Yes, it is true: any unbounded sequence cannot have...
Determine if each of the following series is convergent or divergent. If a series is convergent, find where it converges to. If divergent explain why. (a) n=1 n+(-1)" (b) . =O (c) Lo (2n-1)! (-1)", 20-4
