I want to color different subformulas with overlays successively.
\frame{
\onslide<1>{$$\textcolor{red}{a} \land (\textcolor{red}{b} \lor c)$$}
\onslide<2>{$$\textcolor{red}{a} \land (b \lor \textcolor{c})$$}
}
Unfortunately the formula "jumps" down one line.
I think it's supposed to be something like:
\documentclass{beamer}
\begin{document}
\def\ca#1{\temporal<1>{#1}{\textcolor{red}{#1}}{#1}}
\def\cb#1{\temporal<2>{#1}{\textcolor{red}{#1}}{#1}}
\frame{
$$\textcolor{red}{a} \land (\ca{b} \lor \cb{c})$$
}
\end{document}
What is wrong with simply
\documentclass{beamer}
\begin{document}
\frame{
$$\textcolor{red}{a} \land (\textcolor<1>{red}{b} \lor \textcolor<2>{red}{c})$$
}
\end{document}
?
You can use the \alt overlay specification:
\documentclass{beamer}% http://ctan.org/pkg/beamer
\begin{document}
\begin{frame}
\alt<2>{\[\textcolor{red}{a} \land (b \lor \textcolor{red}{c})\]}
{\[\textcolor{red}{a} \land (\textcolor{red}{b} \lor c)\]}
\end{frame}
\end{document}
You specify the alternate slide (containing the first mandatory argument), while the remaining slides will contain the second mandatory argument.
