The question you ask of sage doesn't really make sense either, so it's perhaps not worth really worrying about the questionable output that sage produces. The underlying package, maxima, doesn't exhibit this tolerant behaviour: (%i10) desolve(diff(y(x),x)+y(x)=1,y(z)); desolve: can't handle this case. however, as you can see when you type "desolve??" (which shows the source), the sage implementation does a lot of pre- and postprocessing. So in the process it seems sage does something that hides the problem for maxima. It's an edge case, but if it bothers you, you can learn how to fix it and submit a patch if you have an idea how to make it behave better. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
