descartes' rule of signs(笛卡尔符号法则)笛卡尔符号法则（Descartes' Rule of Signs）是一个用于确定多项式方程根的数量和类型的数学规则。它由法国哲学家和数学家笛卡尔（René Descartes）于17世纪提出。这一规则对于分析多项式函数的根的正负性质和数量具有重要意义。以下是关于笛卡尔符号法则的详细说明：•笛卡尔符号...

(Descartes' Rule of Signs) 对于任意一个多项式P(x)=anxn+an−1xn−1+⋯+a1x+a0,(an≠0),我们都知道P(x)有n个根(从函数角度来看应该是零点,不过这里其实是想说高次方程的根的情况,所以下文都用根来表述了),包括正根、负根还有虚数根,但是我们很少去研究P(x)到底有几个正根、几个负根以及几...
