Real Analysis
Q: Determine the following limits:
(a) lim((3√n)1/2n), (b) lim((n+1)1/ln(n+1)).
(a) lim((3√n)1/2n), (b) lim((n+1)1/ln(n+1)).
Real Analysis
Q. Let yn=√(n+1)-√n for nϵN. Show that (yn) and (√nyn) converge. Find their limits.
Real Analysis
Q. Explain why the result in question. (show that if X and Y are sequences such that X and X+Y are convergent, then Y is convergent) before theorem 3.2.4 of book real analysis, 3rd edition, by Robert G Bartle cannot be used to evaluate the limit of the sequence ((1+1/n)n).
Real Analysis
Q: If (bn) is a bounded sequences and lim(an)=0, show that lim(anbn)=0 (explain why the theorem 3.2.3 from book real analysis 3rd edition, by Robert G Bartle can not be used)
Real Analysis
Q: Find the limit of the following sequences:

(a) (2n), (b)((-1)nn2)
Real Analysis
Q. show that if X and Y are sequences such that X converges to x≠ 0 and XY converges, then Y converges.
Real Analysis
Q. show that if X and Y are sequences such that X and X+Y are convergent, then Y is convergent.
