也谈二分法求方程的近似解

Also Discussed that the Dichotomy Asks the Equation Approximate Solution

用二分法求方程的近似解是《普通高中数学课程标准》的必修内容之一。利用平分区间及无限逼近的数学思想,是对解析性较好的一元函数避开其复杂运算、近似地计算、有效的解题,是一种行之有效的算法。从另一个角度考虑逼近,会收到良好的效果,结果比教材上的结果更加精确。

Asks the equation the approximate solution is ＂Ordinary High school Mathematics Curriculum Standard＂ one of compulsory contents with the dichotomy law.Mathematics thought which and infinite approaches using the equal division sector,is avoids its complex operation to an analyticity good circular function,to calculate,the effective problem solving approximately,is one effective algorithm.This article considers from other angle to approach,will receive the good effect,the result is more precise than teaching material＇s on result.
