Thanks! Both of these tips are very important to me so extra thanks.

[sage-support] Re: mathjax big braces not rendering properly on sagenb nor publishing properly
Found problem. The mathjax works great if all equations are properly input! However in sage editor, if you have an open span tag and you edit before the end /span tag, it will sometimes do a dreamweaver thing of closing the spantag and reopening it. You cannot see this in the editor. This may happen even if you are inside jsmath / mathjax delimiters. So then you get span tags INSIDE your equation. In jsmath, this still renders properly, in mathjax it does not. Recommendation: Do not edit equations in editor. ALWAYS edit in html mode. (I have had similar problem in wikispaces too.) -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Just adding one more comment for search purposes:
If you see your equation being cut off from text field into sage
field, it means your translator is using 3 braces in a row {{{
Sage interprets {{{ as the beginning of a sage field. So check your
translation.
I had this problem using my equation editor mathjax translator. I
FINALLY figured out the problem.
It had translated the arc length function as sqrt {{{\dot x}^2} +
{{\dot y}^2} + {{\dot z}^2}} . Notice the 3 braces in a row.

I would NOT worry unless someone else complains since:
* I have been moving stuff from the sagenb site to the canterbury site
and now back again. Each has different editors. The canterbury editor
has limited html options.
* I tend to color my text usingspan tags. The canterbury site had
some problems with that (e.g. it would ignore aspan tag followed by
astrong tag).
* I am working with vectors and the (now standard) notation for
vectors is usinga,b,c and of course html uses and as tags.
* I am an interminable reviser which drives editors crazy.

Anyway what happened is:span tags were added inside the mathjax
code:
Example: $x=2$ became $xspan=2$.
jsmath would ignore this addition and process, mathjax would not.
You could not see this addition in the editor, only in the html and of
course my latex was much, much more complex than this example
I'm trying to understand. So someone (not sage notebook) was adding a
span to the tex? Well, if I typed $xspan=2$, I'd expect it to be
interpreted as x less than span greater than equal 2. If you want to
color output, I think using the latex color package inside the dollar
signs (which is supposed to be latex) would be better.
=
This MAY have been the ONLY problem, but (a) I don't know when they
got added and (b) other editing was happening.
=
For sure, the test.sagenb editor does this:
For, I always write \lt which is latex for the less than symbol. The
editor changes this tolt; which is html for this symbol.
Arrays in latex have between the elements in a row. The editor
changes this toamp;
When I type $x\lt y$ in a text cell, then look at the html by clicking
on the Edit button on the right side of the worksheet, I see:
p$x\lt y$/p
When I type
p$\begin{matrix} 3 amp; 4 \\ 5 amp; 6\end{matrix}$/p
But that's okay; Mathjax correctly recognizes amp; as a latex . In
fact, that is what has to happen, since the browser will get confused
with the if that occurs in the html.
=
However, these replacements seem to work in mathjax, but I really wish
editors did not want to help me :)
It sounds like you may want to either click on the HTML button in the
editor, or just go to the edit view of the worksheet that lets you
just type in straight html. Then no editor is getting in the way.
But be aware that you have to encode ampersands as amp; and as lt;
(or \lt, of course), since otherwise the browser will get all confused
when trying to render the html.
Thanks,
Jason

Yes; this has bit me before too. Putting a space between two of the
braces works, IIRC.
By the way, earlier today I was looking at your worksheets, and they
look fantastic!
I did note on one worksheet that you defined a vector-valued function
like this: r=vector((t,t^2,t^3)). You can also define a vector-valued
function like this:
r(t)=(t,t^2,t^3).
Thanks,
Jason

Hiya Jason Thanks Jason for reply! http://test.sagenb.org/home/pub/27 Everything seems to work fine. However, I had to go into the html and fix it a zillion times. I highly recommend keeping the html as simple as possible and always COPYING IT (not the WYSIWYG since sagenb editor seems to add tags that mathjax cannot understand (and you don't see here, but do see in the html)).
