Hi J Elaych,
I am the author of the mentioned worksheet
(http://sagenb.com/home/pub/365/). You can check the new version here :
(http://sagenb.org/home/pub/398/) the old one was full of awful
mistakes, it was for simply testing purposes. I know some C and Python,
etc..., but I am a completely sage newbie and have myself little
experience with any mathematics computing environment (I hope this will
change with Sage, such a nice software!!!!). I had the same hard time
trying to figure out how the notebook() and some general principles of
Sage work, however, it came out to be generally very intuitive (still
far away of being an advanced user).
For LaTeX typesetting what I do is simply the following (I assume
you're in notebook mode).
Version 3.2 or below of Sage
in the worksheet of interest you you can edit html code by clicking in
the big blue "Edit" button (up, just after the blue "worksheet" button).
There you will get a source code form where find that you can simply
type html code between the {{{id=x ///}}} statements (which are indeed
the sagecells). To add LaTeX to your html code just type the LaTeX
formula between $ symbols, for example to type the solution to a second
degree equation type
$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$
Versions 3.3 or above.
Double click on the text, or just shift+click when the blue line
appears bellow the cell to create a new text block (remember, generally
above a Sage Cell). This will make a small html editor of the type '
what you see is what you type" or similar. (TinyCE I think is the
name). There, just apply the same method. Write your text (now you do
not need to edit in html format any more) and edit your formulas with
between $ symbols.
I have the same feeling that there is a little or no documentation to
explain the basic Sage for the newcomer, my recommendation is to follow
this list. This list will provide you with a full source of tips and
tricks and people here are really ready to help (thank you guys!!!!). In
any case, once I am familiar with Sage I am planning to give a course an
introductory sage course in my department to persuade my colleagues to
move from mathematica to sage. Just let me know if I can help you, my
email is just written in the worksheet.
all the best!
Jose.
