Section 10.2 24) S = 1 e - 1 34) Come up with your own counterexamples! (a) The limit of the sequence is not the same at the sum of the series. (b) The N th partial sum is a 1 + a 2 + · · · + a N - 1 + a N (c) The terms tending to zero is necessary for convergence, but not sufficient. (d) The limit of the sequence is not the same at the sum of the series.

Unformatted text preview: a divergent series - that doesn’t help you; the second inequality gives the terms are smaller than terms of a convergent series which allows you to conclude convergence. 22) Diverges (Limit Comparison with X 1 √ n ) 34) Converges (Limit Comparison with X 1 n 2 ) 56) Diverges (Test for Divergence) Section 10.4 8) Diverges (Test for Divergence) Section 10.5 42) Converges (Ratio Test) Section 10.6 12) Converges for x in the interval [-2 , 2), diverges otherwise. 40) Substitute-x for x in the series for 1 1-x for 1 1 + x , then integrate that series to get ln (1 + x ).
