General ⇒ Can margin note be used in the math mode?

[umb365]

Hi all.
I am a new comer for LaTeX. I meet a problem in writing tex.
I wanna add some margin note beside the math equation by \marginpar. but LaTeX tells me: "not in outer par mode".
I have read some documents and searched the internet, but found nothing.
Does LaTeX (or its philosophy) don't "tolerate" margin note in the math mode?

Hope someone can give me some advice.
THANK A LOT advanced.

Hi umb365,

You can control the placement of the marginal notes using \vspace, as the following example suggests:

Code: Select all

\documentclass{book} 
\usepackage{amsmath}

\begin{document} 

text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text
%
\begin{equation}
x^n+y^n=z^n
\end{equation} 
\marginpar{This marginal note will appear after the equation}%
% 
text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text
% 
\begin{equation}
x^n+y^n=z^n
\end{equation} 
\marginpar{\vspace{-3\baselineskip}This marginal note will appear in front of the equation}%
%
text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text 

\end{document}

Of course, according to your needs, you can use any valid LaTeX length as the argument of \vspace.

Additional capability for marginal notes is provided by the marginnote package.

Aha.

Both of them do work!
