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