Now, once again please forgive these questions if they're silly.
Firstly, regarding neatly typesetting text and maths, I've tried the
funky javascript editor (shift+click blue bar), but I don't thinks
it's not quite what I'm looking for. Moreover, I haven't found how to
edit text once it's entered. How is this done?
Double-click on the text.
Ah yes! I guess double-clicking is not an intuitive way of doing it as
single clicking highlights the text. Text one highlights is rarely
treated as buttons or hyperlinks in GUIs. OK, you can highlight links
but it's fiddly. Well, that's my excuse for not figuring that one
out ;-)
Preferrably I'd like to enter sage/python code in the form of a self-
documenting program (actually, there's a better term for this, but
I've forgotten it).
Literate programming
Brilliant, yes! Some long-forgotten cogs are squealing at the back of
my brain.
I'd like to have lots of neatly formatted latex
commentary accomanying my sage code, ie I want to be able to
intersperse latex and sage code. I've done this in the past in latex
(and some programming lanuage) with some extra tools and packages that
extract and compile code from a latex document, run it, then retrieve
and typeset the results.
I've tried using the latex(.) function. It neatly typsets a maths
object, but so far I've only combined it with
text through statements of the form
print %s % latex(object)
which doesn't make for nicely typeset text, headings, piecewise-
defined-equations etc.
Typing %latex at the start of a cell makes all of that cell's content
interpretted and processed as latex markup -- great for the
commentary, but then I can't switch back to sage commands in the same
cell.
OK, maybe I should be content with starting a new cell if I want to
switch from latex entry to sage entry. But then, ideally, I could
still refer to a sage object in a latex cell which would render the
referred object as tex in the latex cell. Thus, I wouldn't need to
manually transliterate a rendered sage expression (say) in to latex in
a latex cell containing commentary of a sage cell.
Am I making sense? Is anything like this possible?
You might check out sagetex
(http://www.ctan.org/tex-archive/help/Catalogue/entries/sagetex.html;
updated version athttp://bitbucket.org/ddrake/sagetex/or installed by
doing sage -i sagetex-2.1.1 )
Sounds like that's what I want, thanks.
It means you are editing a latex document, but you can do all of those
things you mentioned above with sagetex.
Being the first sage material I read, Sage for Newbies appeared to
be prepared in a manner that is exactly what I'm looking for. In it
Ted Kosan briefly mentions speed and presentation usage
styles, and that the latter usage style was the one in which the book
was prepared, but then he leaves the details of usage styles
unexplained and marked only to be developed.
Perhaps if Ted Kosan's source file from which Sage for Newbies was
generated could be made available I could try and pick up the details
from there?
OK. Yes, an OpenOffice file is available. I had the impression that
this wasn't the source but was rather the OO doc was generated from
some other sage session. I'll look in to it.
Ted's book was written in OpenOffice. I thought the source file was in
the same directory. That book hasn't been updated in probably several
years; it may or may not reflect the current nature of Sage. I don't know.
Now, on other silly topics:
I've switched from using sage 3.2 on my machine to using the
sagenb.org server. It seems the latter has poorer typesetting
abilities than v3.2, eg often (but not always) renders sqrt(.) as sqrt
(...) rather than using the usual symbol. Why? Is it something I set?
Finally, regarding this code:
var('X kappa')
X=sqrt(kappa)
F=exp(X)
show(F/F)
-
On v3.2 on my machine the answer is shown as 1, but the sagenb.org
server tells me it's
e^{2*sqrt(kappa)} as though it were showing F*F. What's going on
here?
In the past few weeks, we've switched to a new system for doing
symbolics which is much faster and promises a great future. There are
some patches still going in to better handle the typesetting; these
issues may be associated with the update.
Regarding the code I posted: am I doing something stupid to not get
1 as the answer. I really like the idea of the notebook server, but
at the moment it seems that sagenb.org is not typesetting well (which
you addressed) and is returning faulty answers. Particularly for the
latter reason it's not terribly usable. OK, I'm probably jumping to

As Jason mentioned, this is caused by the switch in the default
symbolics backend. We didn't have enough time to test things
thoroughly. We're tracking the typesetting problem here:
http://trac.sagemath.org/sage_trac/ticket/6211
I just added your example to the ticket.

conclusions in that last sentence... I must be doing something silly
in my code. Perhamps there's some semantic nuance I'm unaware of?
This is a serious bug in the new code we added for simplifying
expressions involving exp's. I made a new ticket for this,
http://trac.sagemath.org/sage_trac/ticket/6256
It's a blocker for 4.0.2. I hope I can get to it before the release
this weekend.
Many thanks for reporting these.

Ted kosan for that. I have several questions.
Immediately I wanted to do some work with sage and am loath to just do
maths without documenting things as I go. Thus I really want to know
how to use Usage Styles, which are mentioned in Kosan's book but not
documented yet. Where can I get info on Usage Styles?
Did he meanhttp://www.python.org/dev/peps/pep-0008/?
I can't find the discussion of usage stlyes
athttp://sage.math.washington.edu/home/tkosan/newbies_book/
Or, at the very least, I'm happy to use print statements, but how do I
print arbitrary TeX math's for markup by jsMath? (ie just as
documentation, not by using show(.) on objects.)
Have you read the tutorial?http://www.sagemath.org/doc/tutorial/index.html
Maybe you are looking for the latex(...) command?
Also, can I expect to be able to use scipy methods from sage, or does
sage generally replace/wrap-up these with its own methods? Where's a
good reference to sage's libraries?
You can use Sage's wrappers to scipy or scipy
directly.http://www.sagemath.org/doc/reference/
Finally, how do I assert variables to be real (or imaginary, or
whatever)? I want to do this to so I can find the complex conjugate of
a symbolic expression by asserting that a variable in the expression
is real.
This should be in the tutorial or reference manual.
Thanks, and sorry if the questions are stupid,
Good questions. Hope you have fun with Sage!

My thoughts up to this point were that the Edit button is mainly for being able to edit and copy the worksheet as a text file, so putting the editor in the Edit page is probably not appropriate. What do you think? How do you suggest we make the editor a more visible part of Sage to the new user? What about changing the new cell (blue) bar so that it had two links, one that said New computation and another link that said New text?

It is worth looking at some of the notebook worksheets on the sage
public server:
http://www.sagenb.org/pub
You can download copies of any of the public worksheets, then load the
copy onto your server. Or, create your own account on the sage public
server, and edit a copy of any worksheet there.
I'm very new to sage myself, so perhaps I have not yet found the
optimum solution. For the moment, I am embedding latex math equations
in html, like:
p align='center'$W_{1}=\frac{1}{2}\rho_{1}V_{1}^{2}SC_{l}$/p
The html explanatory notes go between the cells, and are entered after
clicking the Edit button while viewing a worksheet. You can see an
example of what I created:
