    Your picture didn't seem to get uploaded right.

    But all you want to do is set up a polynomial approximation, like sin(x) = a + bx + cx^2 + dx^3 (and so on), and then keep taking derivatives on both sides until you can solve for a, then b, then c, and so on.

    If you have TI-89 you can check you results by going to the algebra menu and entering taylor if your center is 0.

    Re: series

    It looks pretty good. Except I think you are off by an overall sign. 6-5x-x^2=-(x-1)(x+6).

    Yeah, I noticed it later on, 10x.
