Hi,
I have a general question. Sage incorporates a bunch of mathematical
libraries, if it haven't happened yet, it'll happen soon that two
libraries operate on same mathematical concepts/objects but they
express and represent them differently (trivial example - one library
uses data structures

Hi,
In exploring integration using FriCAS vs. Maxima, I've
noticed that timeit doesn't seem to want to work
for integration.
Taking an example from the Axiom Wiki,
If I do:
var('x')
f = 2*x/sin(x)^2
f.integrate(x)
axiom.integrate(f,x)
all is fine. However, as soon as I try to put a timeit

Can we get this patch (or an equivalent one) into Sage as soon as possible?
I assume we will upgrade to Cython 0.10.1 in Sage 3.2.1, so if Robert
either (a) releases Cython 0.10.2 or (b) feels comfortable

Precisely *exactly* how are you using timeit?! Paste in an exact session.

It's a possibility. If there was a library that only worked for sparse
matrices, but the user wanted to use a function on a dense matrix, I
don't see any way around

Why not to do such translations (from a polynomial to a polynomial)
transparently to the user?
The section you looked at is actually a pretty ugly example indeed and
with the current Sage getting objects from one system to another is
much more elegant.
I see, is it described somewhere?
