hi Jose Luis,
By the error do you mean a NameError? There are no such global
functions defined in Sage.
I would rather use simplify_full and simplify_trig because there would
be easier to discover by a user writing simpl and pressing tab.
On the one hand it is true that for newcomers simplify_full(q) is a
more common sintax than q.simplify_full. On the other hand by the
object oriented nature of python you will never get rid of
class.function sintax entirely and once you get used, I rather tend to
use the second sintax more often.
So the question is if simplify_full is common enough to promote it to
have a top level function.
In fact the function is pretty easy
def simplify_full(q):
try:
return q.simplify()
except AttributeError:
return q
