Comment #1 on issue 1582 by smichr: solve() does not properly back
substitute dummy function variables in limits of Integral
http://code.google.com/p/sympy/issues/detail?id=1582
Does this look more like what you expect?
>>> x=var('x');f=Function('f',dummy=True)
>>> solve(Eq(log(f(x)), Integral(x, (x, 1, f(x)))), f(x))
[exp(Integral(x, (x, 1, f(x))))]
Patch that doesn't break solvers is attached. Also, I notice that
simplification is
not being done in the case of GS_RATIONAL or for the case of multiple
solutions. When
I try to change that I end up breaking a lot of tests...maybe I'm doing
something
wrong. But anyway, the issue at hand is addressed.
