The maxima plugin works! Thank you!

Well, here are some more strange questions:

• Does maxima the only plugin which supports this sort of evaluation? I tried python, r, octave, but none will work.
• And are there some place where I can see which feature a plugin supports?
• I noticed that cos<space>x will drive maxima mad, it requires me to add parents around x. But texmacs formulas have semantic information, and it could be used to improve the interface to CASs I think. So are there any CAS plugin which ultilizes this info?

Thank you again for your time.

Hi proitheus,

please take a look at the Manual (not Jolly Writer) section with title "Plug-ins as scripting languages", where you will find detailed instructions on how to simplify formulae (I tried it now expanding (a+b) (a-b) +2 inside a display equation using Maxima) and linking together executable switches (I did not try it). You get to the Manual sections through the Help menu items; in TeXmacs 2.1.4 e.g. Help->Manual->TeXmacs as an interface, then section 4 of the document that is opened.

Please ask again if you need more information.

Giovanni

The Jolly Writer says:

Some (CAS) systems can also be used in alternative ways, e.g. in order to evaluate a selected _expression_ inside a formula

So I wonder if I can simplify a formula in a normal math environment using some CAS.

Eg

In a display equation, select (a+b)(a-b), do some magick, and the selection turns to (a^2-b^2)
