I need a little help getting started here,(adsbygoogle = window.adsbygoogle || []).push({});

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
