I摘 要在生活中我们通常会看到在我们的账单上的实际金额与支付金额不同的情况,但在这种情况下,我们会看到他们之间的差额其实是很 “小” 的,然而这种“小”在我们的科学学习中却是一种很大的差别. 本文首先给出 5 个具体的数值, 然后根据的相关计算方法来求的近似值.关键词: 近似值; 算法AbstractIn our daily life, we often see the difference between the actual amount on our bill and the amount paid. But in this case, we will see that the difference between them is actually "small", and this "small" is a big difference in our science study. In this paper, five specific numerical values are given first, and then the approximate values are obtained according to the function of correlation algorithm.Keywords: Approximation; Algorithm 目 录摘 要........................................................................................................................IAbstract..................................................................................................................I引言........................................................................................................................1第 1 章 近似值求法................................................................................................41.1 Lagrange 插值多项式..............................................................................41.1.1 线性插值多项式..............................................................................41.1.2 抛物插值多项式..............................................................................51.2 Newton 插值多项式..................................................................................61.3 分段线性插值...........................................................................................71.4 分段三次 Hermite 插值............................................................................81.5 Taylor 定理.............................................................
