The esdiff package has handy macros for derivatives and partial derivatives, taking care of indices.

\begin{document}

  First order derivative: df/dx

  \begin{equation}
      \diff{f}{x}
  \end{equation}

  Fourth order derivative: d4f/dx4|x=1

  \begin{equation}
      \diff*[4]{f}{x}{x = 1}
  \end{equation}

  First order partial derivative:

  \begin{equation}
      \diffp{f}{x}
  \end{equation}

  Second order crossed partial derivative

  \begin{equation}
    \diffp{g}{tu}
  \end{equation}

\end{document}
