## Homework Statement

Suppose I have the following expression:

[tex] (v \frac {\partial}{\partial r} ) f(r,v)[/tex]

I want to obtain:

[tex] \frac {\partial \hat{f}(z,x)}{\partial z} [/tex]

## Homework Equations

[tex] x \rightarrow v/v0 [/tex]

[tex] z \rightarrow (r-r0)/H [/tex]

[tex] H \rightarrow \frac{k_{b} T} {m g } [/tex]

[tex] \hat{f}(z,x) = x^2 f(r,v) [/tex]

## The Attempt at a Solution

[/B]

[tex] x v0 \frac {\partial}{\partial (zH+r0)} \frac{1}{x^2} \hat{f}(z,x) [/tex]

is this possible?
