Comment #3 on issue 1686 by asmeurer: collect() doesn't always collect derivatives correctly http://code.google.com/p/sympy/issues/detail?id=1686
If you put the expand before the collect, you should see the very last test in test_ode.py XPASS. (By the way, I am not expecting anything specific. It just needs to be something that works with the match expressions). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
