Hi Andrey.
Thank you for your response.
However I'm puzzled by your response because if I use wxMaxima and I write cos(theta) the response is cos(θ), if I write cos(θ) (with the Greek character) I also get cos(θ), if I export into Latex I also get \theta, never \vartheta.
I have never seen vartheta as a response of wxMaxima.
When is this line (defprop $theta "\\vartheta" texword) used in wxMaxima?
Thanks,
Daniel Volinski

This is defined in maxima itself. The file src/mactex.lisp, which is used
to produce LaTeX output from maxima, contains
(defprop $theta "\\vartheta" texword)
You can write a short lisp file that redefines this property, and read it
in the beginning of your maxima session (say, from the maxima init file).
(Personally I think that the TeX \vartheta *is* the proper Greek letter
theta. It seems the authors of maxima mactex.lisp think the same.)

I think this can be achieved by editing
src/plugins/maxima/progs/maxima-input.scm
Near the end of this file, add the line
("<theta>" "theta")
Then the TeXmacs character <theta> will be sent to maxima as the ascii
string theta (and this variable is displayed as the real greek letter in
the output).
