I wil answer my own question :) seems that the following function does
the job
def map_simplify_full(x):
return maxima.map('fullratsimp',x).sage()
map_simplify_full(A)
I thought that Maxima computations were replaced by sympy (or
something in Python) in last months. Is it O.K. to continue to use
Maxima inside Sage? Will Maxima be present also in future in Sage? And
is there a way to get function like map_simplify_full without calling
Maxima?
Thanks
