Using Latex, Lyx, or Scientific Workplace for equation editing
Software for equation editing
Lyx is freely available on all standard operating systems and can be downloaded from http://www.lyx.org/ . It has very little learning curve.
Scientific Workplace: (Like Lyx this also has little learning curve, but unlike Lyx it can be expensive.)
Latex for Windows: You can download miktex for
free from
www.miktex.org.
This needs to be used in conjunction with a text
editor. While you could use notepad, an editor customized to miktex makes
everything much easier. One I recommend is winedt (see also their
FAQ)
On unix or linux systems a version of latex called tetex should already be
installed.

Figures can be converted from word to latex by first converting the figure to an eps file: In word, print to a pdf file (requires adobe pdf writer)
and then open the pdf file with pdf writer and re-save it as an eps file
in the same directory as the tex file. Then include the eps figure in your latex
file in the standard way (see instructions on importing graphics )

Notes on some very specific issues
For rotating Figures see http://www-group.slac.stanford.edu/techpubs/help/figures/latex2efigs.html#rotate
Here is another example:
\begin{figure}
\centerline{\fbox{\includegraphics[width=4in,height=6in,angle=270]{figurefilename.eps}}}
\caption{Figure Caption title}
\label{figurelable}
\end{figure}
To make sure floats (e.g., tables or figures) print out before a certain point (say
the end of the section) look at:
http://www.math.upenn.edu/tex_docs/help/faq/uktug-faq/FAQ241.html
who suggest the package placins (add \usepackage{placeins} at the start of
the document). Then put the command \FloatBarrier at the place where you
want to stop the floats (e.g. at the end of the section).
