16007,give solution constants of ODEs unique names,rws,,"(this was reported as part of #6882)
... solving of ode y'=c*x is not correct, the free variable is messed up with a parameter, see [http://groups.google.cz/group/sage-devel/browse_thread/thread/e04cbc547095f2ac sage-devel] - thanks for Yuri Karadzhov
{{{

1/2*c*x^2 + c
}}}
the answer should be something like 1/2*c*x^2^ + c1
The fix depends on closing #8734. The `c` variable that comes from Sage can then be easily recognized, and the constant `c` should then be renamed to `c1` or `_C1`.",defect,closed,major,sage-6.3,calculus,fixed,,kcrisman,,Ralf Stephan,"Nils Bruin, Karl-Dieter Crisman",N/A,,a8df107e76527d83a87456520395ab85dbc44050,,#8734,
