Re: The Rule of Signs

Hi MathsisFun;

So far, so good. The Descartes rule of signs is neat. Can ya give the inventor a mention? He was such a genius.

No one seems to use this in practice anymore. That's a shame, because it is so powerful and so simple.

Well done!


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
