[sage-support] Re: solve(eqts, solution_dict=True) gives IndexError if there's no solution for eqts

This is already mentioned here: http://www.mail-archive.com/sage-support@googlegroups.com/msg20832.html (It seems from that thread that this may not be a problem with Sage itself.) It should be reported as a bug if it hasn't been already. On May 17, 12:20 pm, tvn wrote: > shouldn't this be take

Hello, I just learned that @interact provides a fantastic tool to test mathematical models. I understand that these interactive frames are some sort of Java applets. I wonder If there is a way to export these applets and to make it usable on an ordinary webpage. I know a similar question has been
