Easy second order partial derivative

  1. Mar 18, 2012 #1
    Hello Experts

    I have a simple question.

    Given V as the function of Z and Y,
    Given Z as the function of R and L, [itex]Z=R+s*L [/itex]
    Given Y as the function of G and C, [itex]Y=G+s*C [/itex]
    Assume we also know [itex]\frac{\partial V}{\partial Z}[/itex] and [itex]\frac{\partial^2 V}{\partial Z \partial Y}[/itex]
    If we want to know [itex]\frac{\partial V}{\partial R}[/itex], it will be equal to [itex]\frac{\partial V}{\partial Z} * \frac{\partial Z}{\partial R}[/itex]
    How can we find [itex]\frac{\partial^2 V}{\partial R\partial G}[/itex], by using what is given and known?
