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 agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
