(a) (1 point) If at converges conditionally, then lak| diverges. Answer: True / False (b) (1 point) Suppose that a power series Eck(-a)* converges for - al > R and defines a function f on that interval. The differentiated or integrated power series converge, provided x belongs to the interior of the interval of convergence. It also claim about the convergence of the differentiated or integrated power series at the endpoints of the interval of convergence. Answer: True / False...

True of False (g) does the power series from ∞ to n=1 (x−2)^n /n(−3)^n has a radius of convergence of 3. (h) If the terms an approach zero as n increases, then the series an converges? (i) If an diverges and bn diverges, then (an + bn) diverges. (j) A power series always converges at at least one point. (l) The series from ∞ to n=1 2^ (−1)^n converges?
1. State whether the following statements are true or false. Give reasons for your answer (a) If limko WR=0 then our converges (b) = 5 means that the partial sums converge to 5 (c) E U is called conditionally convergent if it satisfies the conditions of the alternating series test (d) The limit comparison test applies only to series which are positive from some point on (e) (-2)* = 5 (f) If uk = (2k + 1)! then uk+1 =...
