Homework Help: Partial Derivatives

  1. Oct 30, 2008 #1
    EDIT: I got it! I just used implicit differentiation to find it. Thanks for looking in here everyone!


    x2+y2+z2=3xyz
    Find the partial derivatives: zx, zy, and zxy.


    Okay so I know how to find the partial derivative, but I am not sure as to if I need to get the z on one side by itself. If that is what I need to do, then I am actually unsure as to how. I attempted to isolate z and ended up with z=[tex]\frac{x^{2}+y^{2}}{3xy-z}[/tex].

    If I need to isolate z, then that is what I need help in doing. I know how to find the partial derivatives so I'm good there, but the zx, etc., is just kind of confusing since he never went over anything like this in class and the book doesn't have it, either (it always has fx).
