| 摘 要： | 在日常实际应用中,人们会经常遇到求非线性方程f(x)=0的近似根问题。解决这类问题无定法,可用多种方法进行解答。现对"割线法"求解非线性方程近似根的方法,从理论上进行了探讨,并用两种不同的思维方式双点割线法和单点割线法进行讨论,来澄清学习者的一些疑惑,以供参考。

| Abstract: | In the daily life,people ofen run into the problem of nonlinear equation F(X)=0.There are many kinds of methods to solve it.This paper explorates the method of nonlinear approximate equation root of"secant line rule"in theory,and disusses two vertexes of secant line rule and one vertex of secant line rule with two kinds of different thought methods and in order to clear some suspicions of learners,which is used as a reference. |
