“零点定理”在生活中的应用

The Application of “Zero Theorem” in Life

摘要: 在数学发展的历史长廊中，闭区间上连续函数的性质，为数学学科的发展奠定了理论基础。本文主要介绍闭区间上连续函数的零点存在性定理，并例举出零点定理在求解椅子放稳、电梯升降、以及政府对宏观经济的调控等实际生活中的应用，最后归纳总结出应用零点定理求解实际问题的一般步骤。

Abstract: In the historical corridor of mathematics development, the nature of continuous functions on closed intervals has laid a theoretical foundation for the development of mathematics. This article mainly introduces the zero-point existence theorem of continuous functions on closed intervals, and exemplifies the application of the zero-point theorem in solving the problem of chair stabilization, elevator lifting, and government regulation of the macro-economy, and finally summarizes the application of the zero-point theorem general steps for solving practical problems.
