Investigate the Alternating Harmonic Seriesn1and calculate a partial sum that is within 0.001 of the infinite sum. Your answer should include: (-1y A Point or Bar plot of the sequencehich shows at least the first eight elements. A Point or Bar plot of the sequence of partial sums 1 (-_ , which show at least the first eight elements. An estimate of the difference between the fourth partial sum and the value of the series itself, obtained from the plots above. An explanation of how the estimate above relates to the plots above. . A calculation of a partial sum ~1-that is within 0.001 of the value of the series An explanation of how N was obtained
