How do I fix the parentheses and division bar spacing in this quotient of partial derivatives?

With this code:

$frac{left(ffrac{partial left[frac{P}{T}right]}{partialV}right)_T

}{left(ffrac{partial

V}{partial T}right)_V}$

And where:

newcommand{ffrac}[2]{ensuremath{frac{displaystyle #1}{displaystyle#2}}}

I get this:

enter image description here

There are three problems:

1) The parentheses around the outermost numerator don't match the contents.

2) The variables are too close to the division bars.

3) I'd prefer the subscripts be closer to the parentheses.

How do I clean these up, in that order of priority?

I'm using the ffrac code (from Fractions with large elements) to increase the display size; but reverting to the standard frac command doesn't change any of the problems I've described.

I suggest using the esdiff package, which simplifies typing of partial derivatives, and replacing the parentheses in the numerator with a pmatrix environment.

I added a variant to have the column vector in medium size (~80% of displaystyle). The medsize environment is defined in the nccmath package:

documentclass{article}

usepackage{amsmath}

usepackage{esdiff, nccmath}



begin{document}



$displaystyle frac{begin{pmatrix}diffp{begin{bmatrix}

  P\T

end{bmatrix}}{V}end{pmatrix}_{!!! T}}{ diffp*{V}{T}{V}} 

qquad

frac{begin{pmatrix}diffp{begin{medsize}begin{bmatrix}

  P\T

end{bmatrix}end{medsize}}{V}end{pmatrix}_{!!! T}}{ diffp*{V}{T}{V}} $%



end{document}

The best approach uses, I believe, only a single frac expression and inline-fraction notation for both partial derivative terms as well as for the P/T term.

enter image description here

documentclass{article}

begin{document}

$frac{(partial(P/T)/partial V)^{}_T}{%

       (partial V/partial T)^{}_V}$

end{document}
