Hi,

for typesetting radicals in a manuscript for students I use

\DeclareRobustCommand{\radic}{\raisebox{0.75ex}{$\***@th\cdot$}}

however, the dot is so small, that some students overlook it. Replacing
the \cdot with \bullet, however, looks like a fist on an eye. Is there
something in between?

Thanks in advance

Engelbert

There are several other possible sizes of dot, but as you can't change the size of \cdots inside math mode I wrote a little LaTeX file to use the ordinary "."
(usually a full stop or decimal point) which works in either math or paragraph mode. Adjust the horizontal and vertical spacing as you wish.

\documentclass{article}
\DeclareRobustCommand*{\Dotl}{\large{.}}
\DeclareRobustCommand*{\DotL}{\Large{.}}
\DeclareRobustCommand*{\Doth}{\huge{.}}
\DeclareRobustCommand*{\DotH}{\Huge{.}}
\DeclareRobustCommand*{\radical}{\hspace{-0.1em}{\raisebox{0.75ex}{\Dotl}}}
\DeclareRobustCommand*{\Radical}{\hspace{-0.1em}{\raisebox{0.75ex}{\DotL}}}
\DeclareRobustCommand*{\RAdical}{\hspace{-0.1em}{\raisebox{0.75ex}{\Doth}}}
\DeclareRobustCommand*{\RADical}{\hspace{-0.1em}{\raisebox{0.75ex}{\DotH}}}
\begin{document}
OH\radical OH\Radical OH\RAdical OH\RADical

$OH\radical OH\Radical OH\RAdical OH\RADical$
\end{document}

thanks very much, that works like a charm. I'm not sure whether I'll use
\Large or \huge, lets see what the students say.
