Simplifying a factorial

  1. Apr 18, 2007 #1
    1. The problem statement, all variables and given/known data
    (2n-1)!/(2n+1)!


    2. Relevant equations



    3. The attempt at a solution

    ...2n-2*2n-1
    ------------ (pretend that's a divider)
    ...2n-2*2n-1*2n*2n+1

    Is the answer 1/[2n*2n+1]?

    But it would look better with an additional pair of parentheses:
    1/[2n(2n+1)]. I would have been inclined to interpret what you have as
    1/(2n2+1).
