Homework Help: Find ∂v/∂z given 3 equations

  1. Nov 29, 2011 #1
    1. The problem statement, all variables and given/known data

    The equations (x^2)(y^3)(z^3)+uvw+1=0, (x^2)+(y^2)+(z^2)+(u^3)+(v^3)+(w^2)=6, u+v+w=x+2y define u, v, and w as functions of x, y, and z. Find ∂v/∂z when x=1, y=0, z=2, u=1

    2. Relevant equations



    3. The attempt at a solution
    Do I need to solve for v or is there an easier way of solving this problem? I feel like this isnt that hard, but that im overlooking something simple. Thanks for any help.

    Did you consider using the chain rule?
