根的存在定理的推广及其应用

Promotion and Application of the Existence Theorem of Root

本文从闭区间上连续函数根的存在定理出发,通过放宽其条件,得到根的存在定理的几个推论,在对其进行证明的同时给出了具体应用。

Departuring from the existence theorem of continuous function root on the closed interval, through relaxing its conditions, we have got several inferences on the existence theorem of root, and proved them as well as giving a specific application.
