Dear Sebastien, As Pavel suggested LyX already has basic support for various Computer Algebra Systems (CAS) - Maple, Maxima, Octave, Mathematica. Usually you write some math, c-menu on the math inset and select your favourite CAS.
The trouble with this support, and it has been discussed previously on the list, is that it's heuristic in nature and that it may not always work reliably since LaTeX has no mathematically consistent internal representation of the symbolic expressions, and we need to guess what LaTeX means when passing it to Maxima. But look for better explanations in the archive. Maybe if someone looked into making the parser more robust we would get more reliable support for such fancy operations.
