That's because you worded your question like a dumbass user asking someone else to do their homework for him. That's exactly what it looked like so that's exactly the answers you got. Now, if you want people to be more helpful, there's some stuff you have to do: 1. Realise that no-one else can see inside your head 2. Realise that none of us are telepathic 3. None of us are mind readers 4. We don't know what you mean, we only know what you wrote 5. Make it possible for people to help you by clearly stating what it is that you need help on in an unambiguous manner that can be clearly understood. Something like this: ========= start example =========== Hi, I need to solve a bunch of maths equations. Here's an example: [stuff about k, m, n and boundary conditions] I don't need an answer (I already know that using pen and paper), I need to demonstrate the path to a solution, and there's lots more such equations to solve. I had a look in sci-mathematics but nothing there has a likely looking name,a nd the download size leads me to believe most of them are overkill for this. Anyone have experience with this kind of thing and can recommend an entry- level app that gets the job done easily? ============== end example =================== Now, a mail like that would have gotten you lots of recommendations, would have sparked a fascinating debate on how to solve it programatically, probably produce 9 solutions in 4 languages in the first 6 hours and also include a detailed treatise on why portage might be able to do it but revdep-rebuild cannot (by design). See where I'm going with this? -- alan dot mckinnon at gmail dot com
