Question: Is there a way to obtain a pdf file without figures and tables, while maintaining the figure numbers in the body text.

Thank you very much

Answer: 
That picture looks like 

```
\(\left(\frac{\partial U}{\partial T}\right)_V\).

```
The `esdiff` package makes it easy to type: the `\diffp*` command accepts 3 arguments (function in numerator, variables in denominator, evaluation point). It can calculate by itself the order of derivation in crossed derivatives. 

You have options to have the differential symbol upright (default) or italic, and to set horizontal spacings between the differential symbol and what follows, or between the differential symbols of variables for crossed derivatives.

```
\documentclass{article}
\usepackage{amsmath} 
\usepackage[thinc]{esdiff}

\begin{document}

\begin{gather*}
\diffp*{U}{T}{V}\quad \diffp*{f(x,y )}{{x^2} y}{(x_0,y_0)} \\
 \diffp{f}{xy} = \diffp{f}{yx}
\end{gather*}%

\end{document} 

```
