Find the Maclaurin series for the following function

  1. May 15, 2013 #1
    1. The problem statement, all variables and given/known data

    f(x) =ln (1-x^3) / (x^2)

    2. Relevant equations

    Using the maclaurin series ln (1 +x) = Ʃ (-1)^(n-1) (x^n)/(n)

    3. The attempt at a solution

    the maclaurin series for the function i get is [(-1)^(2n-1) (x)^(n)] / (n)
    however, the answer according to my prof is [(-1)^(2n-1) (x)^(3n-2)] / (n)
    How???

    How about showing your steps ?

    What is the Maclaurin series for ln(1-x) ?

    Then what is the Maclaurin series for ln(1-x3) ?
