Problem

A scientist models a damped oscillation by the alternating series V=∑n=1∞(−1)n+1 ln⁡nn3/2.V=\sum_{n=1}^{\infty}(-1)^{n+1}\,\frac{\ln n}{n^{3/2}}. Answer the following questions related to the model. (a) Verify that the series VV converges. Present a complete argument that addresses every required condition. (b) The scientist wants the first NN partial sums SNS_N to approximate VV with an absolute error less than 0.0010.001. Determine the smallest integer NN that guarantees this level of accuracy, and justify your answer.
