Homework Help: Power series when variable is very large

  1. Aug 15, 2011 #1
    1. The problem statement, all variables and given/known data

    Find first three non zero terms in series expansion for ln(1+e^-z) when z is very large

    2. Relevant equations

    3. The attempt at a solution

    I've got as far as ln(1+e^(-1/z)*e^((1/z)(z^(2) - 1))

    not sure where to go from here
