Newtonian notation for derivates on latex

Question

I am using Notion for my studies: so I have to use Latex to represent the equations or others math stuffs. I noticed that I can use the Newtonian notation on Latex with the command \dot or \ddot (first derivative and second derivative) but I cannot represent the third with \dddot or with something else. Is there a way to represent that?

Answer 1

As in this other answer, three dots (\dddot) and four dots (\ddddot) in math mode require the package amsmath.

So you have either

\documentclass{article}

\begin{document}

\[\dot{x}\]

\[\ddot{x}\]
    
\end{document}

or

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\[\dot{x}\]

\[\ddot{x}\]

\[\dddot{x}\]

\[\ddddot{x}\]

\end{document}
