The chain rule (PDE)

  1. Feb 8, 2012 #1
    Im new on the forum, so I hope you guys will have some patience with me :-)

    I have a question about the chain rule and partial differential equations that I cant solve, it's:

    Write the appropriate version of the chain rule for the derivative:

    ∂z/∂u if z=g(x,y), where y=f(x) and x=h(u,v)

    I have tried to do a dependence chart of it, but it's just not working for me.

    Thank you very much.

    Draw a diagram. It is pretty straightforward.
