Homework Help: Taylor series

  1. Aug 4, 2010 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations



    3. The attempt at a solution

    I have the same final answer except without the X/2 + power series(n=1), I just have the same power series except its n=0.

    Is there any reason why they are pulling out n=0 and changing it to n=1?

    I did a similar problem which seems I could do the same thing but they left it as n=0.

    The product in the numerator, 1x3x5x...x(2n-1), doesn't really work out for n=0.
