Implicit function theorem

  1. Aug 4, 2007 #1
    1. The problem statement, all variables and given/known data

    Understanding the proof of the implicit function theorem.

    2. Relevant equations

    May assume the inverse function theorem.

    3. The attempt at a solution

    I'm following a proof given on the net:


    since I'm unhappy with my lecturer's explanation.

    The only thing I'm not clear about in this proof is the fact that the inverse function h is of the form [itex]h(x,y) = (x,k(x,y))[/itex] for some differentiable function k. Apparently this is clear but I just don't see it.

    Any help would be appreciated.
