So |$\diffp{f}{{x^2}}$| gives $\diffp{f}{{x^2}}$. +% +%We can mix options: +% |$\diffp*{f}{{x^2}{y^3}}{z}$| +%gives $\diffp*{f}{{x^2}{y^3}}{z}$. +% +%\section{Options} +% +%Several options are available: +%\begin{itemize} +%\item +%by default, derivatives are written in displaystyle on text mode. +%The \textsf{display} option set this default. With the \textsf{text} +%option, derivatives are written in textstyle on text mode; +%\item +%by default, the \texttt{d} of the derivative is written in roman. +%Available options are \textsf{roman} and \textsf{italic}; +%\item +%we can set the space between the \texttt{d} and the symbol of the +%function or of the variable. By default, this space is null. +%Available options are \textsf{thin}, \textsf{med} and +%\textsf{big}. It may be fine to add a space when the \texttt{d} +%is in italic; +%\item +%We can set the space between the $\partial$ and the symbol of the +%function or of the variable. By default, this space is null. +%Available options are \textsf{thinp}, \textsf{medp} and +%\textsf{bigp}; +%\item +%the space between $\partial x$ and $\partial y$ in crossed derivatives may be too +%narrow.
