Pde help

  1. Feb 10, 2006 #1
    I need a little help getting started here,

    Show that the boundry conditions X(b)=wX(a) +zX'(a)

    and
    X'(b) = yX(a) + dX'(a) on the interval a<=x<=b are symmetric if and only if wd-zy=1

    i know that the a set of boundries are symmetric if f '(x)g(x) - f(x)g'(x) = 0 evaluated at x=a and x=b. but i am confused on what f(x) and g(x) would be.
    if some one can help me get this problem started it would be greatly appreciated.

    thanks

    What would it mean for the BC to be 'symmetric'?

    X(a) = X(b) and X'(a) = -X'(b) perhaps.
