I am creating notebooks to publish for my students to use in a spring
course. Perhaps not surprisingly, I am interspersing commands, output
of those commands, and explanatory text. The only way I know to
create the latter is to shift-click to open a text cell. I discovered
a few days ago that I can type LaTeX math-mode things that get
formatted as I would hope when the cell contents are saved: things
like $x^2 + y^2$. But not everything works. I do not get Greek
letters, for instance, when I embed $\alpha, \beta, ...$ in my text
cell. I do not get a radical sign when I type $\sqrt 3$. The equation
$x = \rho\sin\phi\cos\theta$
was rendered exactly as it is typed above (with the backslashes)
except that no dollar signs were displayed. Is there a way to do
this? (I must admit that I didn't thoroughly search the reference
manual before asking this question, but I did search previous
submissions to the Sage-support list, and one thread suggested that
what I attempted above should, indeed, work.)
I should mention something else, in case it is relevant. I am running
Sage inside a browser (Mozilla 3.5.7), using the "kernel" (is that the
right way to think of it?) at www.sagenb.org. For most of today, when
I open up a notebook I get the message
"The page at http://www.sagenb.org says: It looks like jsMath failed
to set up properly (error code -7). I will try to keep going, but it
could get ugly."
I cannot think of anything I've done which made this begin happening,
but the message reappears if I click on the jsMath button in the
bottom right corner and select "Reload". Does this have anything to
do with my typesetting issue?
