8. Prove that if two rational sequences (a)1 and (n)1 are equivalent, then (a) (an) is Cauchy if and only if (bn) is Cauchy. (b) (an) is bounded if and only if (%) is bounded. 8. Prove that if two rational sequences (a)1 and (n)1 are equivalent, then (a) (an) is Cauchy if and only if (bn) is Cauchy. (b) (an) is bounded if and only if (%) is bounded.
Provide an ? N proof to prove that the following sequences converge. Question (e), please. 5. Provide an e – N proof to prove that the following sequences converge. (a) {ne cos(n)} (b) {zo Bom} (c) {(-1)In (n)} (d) an = 2 + 1 (@) an = V1 -
This assignment asks you to prove the following Proposition 1 Let {n} and {n} are two sequences of real numbers and L is a number such that (1.a) un → 0, and (1.b) V EN, -L Swn. We illustrate the proposition. To begin, one can check from the definition that 1/n 0. This fact, plus the arithinetic rules of convergence, generate a large family of sequences known to converge to 0. For example, 11n +7 1 11 +7 3n2 -...
Let (In), and (yn).m-1 be sequences such that Pr – yn| < 1/n for all n. Use the definition of convergence to prove that, if (2n)_1 is convergent, then (Yn)-1 is convergent.
, then n lim Let Ά be a square matrix. Prove that if ρ(A)<1 Use the following fact without proof. For any square matrix A and any positive real number ε , there exists a natural matrix norm I l such that l-4 ll < ρ (d) +ε IIA" 11-0
Let ao 2 bo > 0, and consider the sequences an and bn defined by an + bn n20 (1) Compute an+l-bn+1 1n terms of Van-v/bn. (2) Prove that the sequence an is nonincreasing, that the sequence bn Is nonde- creasing, and that an 2 bn for all n 20 (3) Prove that VanVbn S Cr for all n20, where C> 0 and y>1 (give values of C and γ for which this inequality holds). Conclude that an-bn C,γ-n, where...

2. (D5) Let n = o(a) and assume that a =bk. Prove that <a >=<b> if and only if n and k are relatively prime.
please i need the question (m) (n)(o) for the detailed proof and example ! thanks ! Prove that the given statements are true concerning the two sequences of real numbers (an) and (b. 0 and limn→” an-L > 0, then (m) If an, bn lim an) (lim supbn) lim sup (anbn) - (n) If an > 0 and bn > 0 and if both lim supn→ooan and lim supn→oobn are either finite or infinite, then lim sup,-,(anbn) < (lim sup,-o...
