- Determine whether the sum of the infinite series is defined. k=115(0.3)karrow_forwardProve the formula for the sum of the first n terms of an arithmetic series: a+a+d+a+2d+a+n-1d=na+an2 where an=a+n-1d.arrow_forwardFor the series i=1510i find (a) the fourth partial sum and (b) the sum. Notice in Example 9(b) that the sum of an infinite series can be a finite numberarrow_forward
- Find the sum of the infinite geometric series. k=113(15)k1arrow_forwardFor the following exercises, use the geometric series k=1(12)k 28. Graph the first 7 partial sums of the series.arrow_forwardCalculate the first eight terms of the sequences an=(n+2)!(n1)! and bn=n3+3n32n , and then make a conjecture about the relationship between these two sequences.arrow_forward
- 44. Assumptions Matter In 1829, Lejeune Dirichlet pointed out that the great French mathematician Augustin Louis Cauchy made a mistake in a published paper by improperly assuming the Limit Comparison Test to be valid for nonpositive series. Here are Dirichlet's two series: IM8 Σ (-1)" √n Σ n=1 (-1)" √n (-1)" √n Explain how they provide a counterexample to the Limit Comparison Test when the series are not assumed to be positive.arrow_forwardUse series to evaluate the limitsarrow_forward26. Practice similar Help me with this Consider the series Answer: L: = ∞ n=1 5n (n+1)4²n+1° Evaluate the the following limit. If it is infinite, type "infinity" or "inf". If it does not exist, type "DNE". lim n→∞ an+1 an - L What can you say about the series using the Ratio Test? Answer "Convergent", "Divergent", or "Inconclusive". Answer: Convergent < Previous Determine whether the series is absolutely convergent, conditionally convergent, or divergent. Answer "Absolutely Convergent", "Conditionally Convergent", or "Divergent". Answer: Absolutely Convergentarrow_forward
- sum Sn. (b) Use (a) to determine whether the series is convergent or divergent. 8 (5) Decide whether each of the following statements is true or false. If a statement is true, explain why. If a statement is false, provide specific examples of ak and Σb for k=1 which the statement is false. Σ (a) If 5 am is a series such that ak a k=1 1 k² < ak for all k, then (d) If ak k=1 (b) If ak is a series such that 0 < aarrow_forward5. Consider the series n! n=0 for real numbers x. (a) Use the ratio test to determine the values x for which the series is absolutely convergent. (b) Does this mean that the series is convergent for these values of x? Explain. (c) Explain how one can use part (b) above to determine the limit of the sequence {an} where 22n an n!arrow_forwardarrow_back_iosarrow_forward_ios
