Accurate to first order

  1. Oct 7, 2009 #1
    1. The problem statement, all variables and given/known data
    [tex]
    x^{-1/2}(2-x)^{-1/2}
    [/tex]

    1) approximate to lowest order in x
    2) approximate to next order in x

    Do I apply the binomial expanion?
    2. Relevant equations



    3. The attempt at a solution

    That seems like a good idea.

    [tex]

    x^{-1/2}(2+x/2)

    [/tex]

    [tex]

    2x^{-1/2}(1/2+x^{1/2})

    [/tex]

    lowest order is 2x^(-1/2)?
