Maclaurin Series

  1. Jan 25, 2009 #1
    1. The problem statement, all variables and given/known data
    Find the Maclaurin series for f(x)= 1/ (1+x+X2)


    2. Relevant equations



    3. The attempt at a solution

    I think the book says I can just divide 1 by the Maclaurin series of (1+x+X2). And when i do this the original function is the answer (which makes sense).

    But when I do it my finding the derivatives of f(x) and then using the formula I get f(x) = 1-x+x3.

    So I was wondering if
    1) Which way is correct
    2) is the second one accurate.

    Thanks

    The second way is accurate. The first way would be as well if you do what they want you to. You are supposed to divide 1 by 1+x+x^2 using polynomial division. The result is NOT 1+x+x^2.
