Thanks andrew that was an interesting read! Yes about zeros! also one should always be mindful that div/(a-a) appearing in symbolic solutions during manipulation are not checked, it makes certain problems solvable in real time, but can miss sol'n. I'm not sure the inductions hold for all eq'n under Solve. And how mathematica solves given {}, that may change between versions. I wouldn't use the inductions myself. I'd supply the options and check the answer. (I've never needed to use Solve programatically yet) I don't have the Solve source code and it's not my job to know it really. Would be nice if I had such a collection and was paid to tend it :) I'm saving the mail and reading again later. Thanks - John
