Confusion with Taylor series

  1. Apr 7, 2013 #1
    1. The problem statement, all variables and given/known data

    f(x)=[itex]\frac{4x}{(4+x^{2})^{2}}[/itex]


    2. Relevant equations

    [itex]\frac{1}{1-x}[/itex] = [itex]\sum[/itex] x^{n}

    3. The attempt at a solution

    How am I supposed to use that equation to solve the main problem. I have the solution but I don't understand how to do any of it. My professor is horrible, been on academic probation for 7 years, and doesn't teach us anything. Just writes on the board

    Sorry I meant to say MacLaurin series. A friend told me I have to solve it using infinite series but that still has me confused
