o0 1 (% 3% r) Suppose you want to approximate the series E F by its partial sum, with an error of no more than n2 n=1 1000 (a) Use the error bound from Problem 22 of this assignment to bound the error incurred by approximating Z W|th Z n=1 Ii#il (b) Find the smallest whole number N such that the quantity in the rightmost blank above is no more than N (c) You set up a spreadsheet to calculate Z n=1 content of a cell is copied down its column. The first row consists of labels. Assume the table continues vertically for as long as necessary. 1 1000 = using your value of NV from (b), as shown below.
