The series S=∑n=1∞(−1) n+11n3S=\displaystyle\sum_{n=1}^{\infty}(-1)^{\,n+1}\dfrac{1}{n^{3}} is approximated by the partial sum S5S_{5}. Calculate the maximum possible absolute error when S5S_{5} is used to approximate SS, and determine whether this approximation satisfies the requirement that the error be less than 0.0020.002.
