I noticed a couple of things on sage-devel recently about integration with Maxima. It appears Maxima can't do either of these two. (Well, it does the second one, but leaves it in a overly complex form, that Sage's n(). can't even use).
integrate( sqrt(x^2+4)/(x^2+1), x ) integrate(log(1+x)/(x^2+1),(x,0,1)) # (This one from the Putman 2005 challenge) I noticed that if one sticks that exact syntax into Wolfram|Alpha, it evaluates the integrals. There's no need to re-write the integrals in Mathematica's syntax.. If one was to use Mathematica directly, then the sage syntax would not be understood. I guess none of this is not totally surprising, but can be useful to get a second opinion on something, without even taking the trouble to rewrite the problem in Mathematica's syntax.
