Math & Science ⇒ Symbol strictly upon another one in Math Formula

[Hrs]

Hi all!

How can i place in a formula one symbol strictly upon another with shortening upper one?

Lower symbol must not to crawl anywhere (i.e. for example solution with array is not valid).

It's better to have generalized solution, but urgently i need to place a small circle upon a symbol. Help me please.

Hi,

welcome to the board!

You could use a ring accent, i.e. \r{x} in text mode or \mathring{x} in math mode.

Thank you very much!

But there is a way to make "o" smaller?

[Stefan Kottwitz]

Another way, using the accents package:

Code: Select all

\documentclass{article}
\usepackage{accents}
\newcommand*{\overcirc}[1]{%
  \accentset{\circ}{#1}}
\begin{document}
$\overcirc{x}$
\end{document}

Instead of \circ, you could use any other symbol, perhaps you would find a smaller circle in the symbols list.

Thank you very much!

In addition, i found an alternative way to do that. It might be useful for someone.

Code: Select all

\usepackage{amsmath}
\usepackage{graphicx}
$\overset{\text{\scalebox{0.25}{$\circ$}}}{x}$

Or basing on your solution, result's are better:

Code: Select all

\usepackage{graphicx}
\usepackage{accents}
\newcommand*{\overcirc}[1]{%
  \accentset{\text{\scalebox{0.5}{$\circ$}}}{#1}}
