(c) Use Cauchy's principle to show that the harmonic series n = 1 ∑ ∞ n 1 does not converge. (d) Prove that if the series n = 1 ∑ ∞ a n is divergent, then so is n = 1 ∑ ∞ c a n where c ∈ R, c = 0.
WebWhen asked to show if a series is convergent or divergent you might spot that such series is "mimicked" by a positive, decreasing and continuous function (there's no fixed rule, you have to train your mind to recognize these patterns). If that is the case you can use the integral test to say something about the series and back it up properly. WebDetermine if the series converges or diverges. Use any method, and gve a reason for your answer: ∑n=1∞4nsin2n Does the series comverge or diverge? A. Because ∑n=1∞4nsin2n≥∑n=1∞n1 and ∑n=1∞n1 diverges, the series diverges by the Direct Comparison Test. B.
