Yes, it should be easy. Have a look at :
http://lists.gnu.org/archive/html/texmacs-dev/2007-05/msg00091.html

For a basic example, as well as for a summarization of the TeXmacs
tree API. The only missing function in the message above is:
[[
(cursor-tree) -> TREE
]]

, which gives you the position of the cursor in a tree. Another
function you will need probably is a function to get the parent
of a tree :
[[
(define (tree-up1 t)
  (with p (tree->path t)
     (if (> (length p) 2)
         (path->tree (cDr p))

[sage-devel] WMI2 has been released

Dear Colleagues and Friends,

we are happy to announce WebMathematics Interactive 2.0 (WMI2) which has been released a few hours ago.

WMI2 is currently a graphical web front-end for the Maxima CAS and Gnuplot, the GNU function plotting utiltiy. What's more, WMI2 can be easily extended to be a front-end for arbitrary CAS or other mathematics software.

We focus on education and ease of use. The targeted group of students are at age of 14-21. Normally the users should not know any kind of syntax of the underlying CAS. Our development was supported by University of Szeged, Hungary and Ministry of Education and Informatics (back in 2003). The alpha version of this software has been presented to an expert audience at the CADGME conference, Pécs, Hungary, June 2007.

The current version offers 50 different kinds of computations for 5 different areas of mathematics. The previous (1.0) version of our software has been continously used in education at University of Szeged and other colleges and universities world-wide. We humbly appreciate all kind of feedback of your experiences trying out the new version of WMI.

More information:

* On-line demo: http://matek.hu
* Documentation: http://matek.hu/doc (including 3 short movies in English and 3 in Hungarian)
* Download area: http://matek.hu/downloads/
* Old version: http://matek.hu/1
* Details of development: http://wmi.math.u-szeged.hu/~kovzol/cadgme.php (obsolete)
* Contact: info <at> matek.hu

Re: WMI2 has been released

where should we send in bug reports?

Here is one or two.

integrate(sin(w*t)*e^(-s*t),t)
gives an answer that looks ok except for the log(e) parts ---

but when i click on it to move it to the input window -- it reports an 
error   -- the window is pink.

here is what is in the window:

-%e^-(log(e)*s*t)*(log(e)*s*sin(t*w)+w*cos(t*w))/(w^2+log(e)^2*s^2)

If I delete the % symbol then it is ok.

now for the second part

when I factor it --- it returns:

 -%e^-(s*t)*(s*sin(t*w)+w*cos(t*w))/(w^2+2*s^2)
and this has a % sign in it ---but more importantly the last term is
2*s^2   and should only be s^2
