Above point in latex

Question

I would like to know how to make a point above a symbol (ie : ẋ) I tried \overset{.}{x}, but the point is very small... Can you help me ? Thanks

Answer 1

Just to write down one answer, elaborating a bit the source cited in the comments, and to add the following minimal codes.

\documentclass{article}

\begin{document}

$\dot{x}$

$\ddot{x}$
    
\end{document}

One dot (\dot) and two dots (\ddot) work in math mode as above. Three dots (\dddot) and four dots (\ddddot) the same but they require the package amsmath:

\documentclass{article}
\usepackage{amsmath}

\begin{document}

$\dddot{x}$

$\ddddot{x}$

\end{document}

Instead in text mode, the package called stackengine may help:

\documentclass{article}
\usepackage{stackengine}

\begin{document}

\stackon[1pt]{x}{.}

\end{document}
