Comment (by tjlahey):
I've noticed this many times when running my integration tests. Axiom
handles these kinds of integrals by returning multiple solutions. Maxima
could do the same and that's what I think is the best solution.
One possible solution on the Sage side would be to add optional parameters
to answer the questions. So, the first time one tries the integral, you
get the trackback so you re-run the integration with an added parameter to
answer the question (or series of questions for problems with several
branches).
Since the questions are yes/no based, another option arises, that is more
difficult to implement but better for the user. This would be to have an
option for Sage to build up the branches by re-running the integration
answering the questions automatically and noting the solution and the
question+answer.
Both of these Sage solutions require improvements to the pexpect interface
which are likely non-trivial.
