Basically, I want to have a X with tilde ontop of X.

enter image description here

I tried to follow:

\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}

\begin{document}
$\backsim\ \sim\ \thicksim$
\end{document}

But this only output tilde

from How to draw a tilde in math mode

    What about $\tilde{x}$? – Willie Wong Jan 13 '20 at 21:18
  • You can try also widetilde (more greater than tilde) \documentclass[a4paper,12pt]{article} \usepackage{amsmath} \begin{document} $\widetilde{x}$ \end{document} – Sebastiano Jan 13 '20 at 21:27
  • Combinations of letters and diacritics are not generally provided as single symbols; in fact, I can't think of a single one. The mechanism to be used is shown in the comment by @WillieWong. – barbara beeton Jan 14 '20 at 19:34

$\tilde{x}$

why is it so problematic?
