I need to make "wide dot" for time derivative.

I followed what is written here : How to make a larger "\dot"

I have put 

    \usepackage{amsmath}
\usepackage{accents}
\newcommand*{\dt}[1]{%
  \accentset{\mbox{\large\bfseries .}}{#1}}
\newcommand*{\ddt}[1]{%
  \accentset{\mbox{\large\bfseries .\hspace{-0.25ex}.}}{#1}}

In Latex Preamble in Lyx document settings.

However in mathmode (CTRL-M), if I write 

\dt{x}

It doesn't display an $x$ with a dot above.

How to fix it ?

  • Why not just use the standard TeX commands \dot x and \ddot x ? (In math-mode, of course.) ` –  Jun 02 '19 at 11:22
  • @Andrew because the dot are very small and barely lisible over the letter –  Jun 02 '19 at 11:32
