    Sum of a series using partial fractions.

    (a) Express the function as the sum of a power series by first using partial fractions.


    Well I ended up getting the entire problem wrong. I still don't know the series notation or the interval of convergence.

    Well, express it as partial fractions, by noting that 10 = (x+1)-(x-9) , or otherwise.

    Then you'll need to use \displaystyle \frac{1}{1-t} = \sum_{n \ge 0}t^n for |t| < 1.
