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.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
