I was trying to typeset the time derivative of \vec{r}_\alpha
, and naively, I put it as an argument to \dot
. This does not work: the arrow is not on r
anymore. Here is a minimal example:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
\dot{\vec{r}_\alpha}
\]
\end{document}
Note that there is a better way to typeset it (and it works): \dot{\vec{r}}_\alpha
. I am asking out of curiosity.

Have a look at the mattens package. I have written it to "overcome" these problems
