Hi all:
I am trying to get the time derivative of the mean value of a variable.
To
implement the mean value of a variable I defined in the preamble:
\newcommand{\mean}[1]{<#1>}
and in the lyx file I typed:
Alt-m d \dot{\mean{x
The final output in tex is something like that
\[
\dot{{}\mean {x}\]
If I type Alt-m d \dot space \mean{x
the tex output is:
\[
\dot{\mean }{x}\]
which both of them are completely wrong, because I would like to obtain
\[
\dot{\mean{x}}\]
I guess that there is a problem with \dot in math mode, but maybe I have
missed something important. What am I doing wrong? How can I do?
Thanks in advance for your help
