Homework Help: Estimated Sums in Infinite Series Problem

  1. Jan 30, 2013 #1
    1. The problem statement, all variables and given/known data
    How many terms of the series do we need to add in order to find the sum to the indicated accuracy?
    Ʃ((-1)n)/(n(10n)) from n=1 to infinity
    |error| <.0001

    I keep ending up with n=log(4)-log(n)
