Comment #3 on issue 1766 by asmeurer: expand(power_base=True) is too aggressive http://code.google.com/p/sympy/issues/detail?id=1766
I don't know why that one doesn't work, when separatevars can do it. That is another issue (issue 1767). I agree to put an assumptions argument in power_base. expand(log=True) also has assumptions problems, but it you fix them, it breaks the integrator. I think the problem with ODEs is that if you have an ODE, you don't necessarily know right off how the domain of the solution will need to be restricted in order for it to be correct. So it isn't just a simple matter of changing the assumptions on the variables to make it work, in the general case. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
