| 摘 要： | 高等数学中的零点定理是闭区间上连续函数的一个重要性质，利用它既可以证明方程根的存在性或求根的近似值，即解“等式”问题，又可以解“不等式”问题，本文从生活中谈谈零点定理的几个应用，以达到在数学教育教学中理论与实践相结合的作用。

| Abstract: | Theorem of zero point in Advanced mathematics is an important property of continuous function in close internal. The theory can be used to prove the existence of the root of equation or get the approximate value of root,that is,to solve the problem of quality and inequality. Firstly, the paper introduces the application above in two aspects. Furthermore, it also discusses the application of theorem of zero point in our life, to achieve the goal of combining theory and practice in mathematical education. |
