I've seen the tutorial, but need something more. How do I know what 
folder I'm in? How do I move from where I am to, for example, 
C:\abc\def? So far I've tried various combinations like this:
cd ..
cd C:\
pwd (yes, I know it's not windows)
I tried %cd .., and that may have moved me but I seem to get back to the 
same place.
I seem to be in C:\Documents and Settings\administrator. If I doa %cp 
..\\ it looks like I get to C:,円 but follwing that with pwd gets me back 
to where I started--C:\Documents and Settings\administrator.
If I want to execute a program with %run, I need to be where abc.py is 
or, perhaps say something like %run C:\myPyPrograms\abc.py.
Dir doesn't work and I haven't been able to even see what's in the folder.

All,
If I am using this in my conf.py in Sphinx:
extensions = ['matplotlib.sphinxext.mathmpl',
	'matplotlib.sphinxext.only_directives',
	'matplotlib.sphinxext.plot_directive']
Is there a way I can use ams-latex constructs such as:
\begin{align*}
x+2y&=3\\
2x-3y&=4
\end{align*}
