Homework Help: Finding mclauren series for the following function

  1. May 19, 2009 #1
    i am given the function f(x)=x/(9+x2), i am sasked to find the mclauren series,, what i have done is actually found the 1st 2nd 3rd 4th derivative of the function at x0=0 and found the regularity,, but i think that i am expected to use one of the given series' and use deformation, the problem is that i cannot find an appropriate series, the best i can find is

    1/(1+x) the problem being that i have a 9 instead of a 1 in my denominator,

    If that is the only problem you have then try [itex]9+x^2=9(1+(\frac{x}{3})^2)[/itex].
