Comment #6 on issue 3149 by nicolas....@gmail.com: solve() could attempt
logcombine when looking for solutions
http://code.google.com/p/sympy/issues/detail?id=3149
A much simpler failing example :
In [1]: solve(log(x+1)-log(2*x-1))
---------------------------------------------------------------------------
[...]
NotImplementedError: multiple generators [log(2*x - 1), log(x + 1)]
No algorithms are implemented to solve equation log(2*x - 1)
(Solution is obviously 2.)
However, I think it should work without having to set manually 'force=True'.
So, logcombine should be attempted, and then, it is up to checksol() to
eliminate "false positives", or solutions which don't match assumptions.
