Second order partial derivative question
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?
