8.(1 pt) Each of the following statements is an attempt to3. For alln>1,n6-n3<1n2, and the series1n2converges,so by the Comparison Test, the seriesn6-n3converges.4. For alln>1,1nln(n)<2n, and the series 21ndiverges,so by the Comparison Test, the series1nln(n)diverges.5. For alln>2,ln(n)n2>1n2, and the series1n2converges,so by the Comparison Test, the seriesln(n)n2converges.6. For alln>1,arctan(n)n3<π2n3, and the seriesπ21n3con-verges, so by the Comparison Test, the seriesarctan(n)n3converges.Correct Answers:CCIIIC9.(1 pt) For each of the series below select the letter fromA to B that best applies and the letter from C to G that bestapplies. For example, if a series is convergent by comparisonwith a p-series type AE for that series.A. The series is convergent.B. The series diverges.C. The series is a p-series.D. The series is a geometric series.E. We can decide whether this series converges by com-parison with a p-series.F. We can decide whether this series converges by com-parison with a geometric series.G. The terms of the series do not have limit zero.1.n=1cos2(nπ)nπ
show that a given series is convergent or divergent not using theComparison Test (NOT the Limit Comparison Test.) For eachstatement, enter C (for ”correct”) if the argument is valid, orenter I (for ”incorrect”) if any part of the argument is flawed.(Note: if the conclusion is true but the argument that led to itwas wrong, you must enter I.)1. For alln>1,ln(n)n2<1n1.5, and the series1n1.5con-verges, so by the Comparison Test, the seriesln(n)n2converges.2. For alln>2,nn3-8<2n2, and the series 21n2con-verges, so by the Comparison Test, the seriesnn3-8converges.
