It is the promotion of the mean value theorem in calculus, is also an important tool for the application of higher order derivatives of the functional state. Taylor formula in the calculus of the various fields have important applications, and the Taylor formula for complex simple function in the mathematical field of research has played a significant role. This article in addition introdution Peano remainder and Lagrange remainder term of Taylor formula commonly used in approximate calculation, the limit inequality proof to determine the function extremum for solving prove, in particular, A detailed introduction of the Taylor formula in the application of the function bump and the inflection point judgment, the judgment of convergence and divergence of series and generalized integral, determinant calculation, and the article discusses a new method to prove that the Taylor formula, further Taylor formula to the more general form. Keywords: Taylor formula; Peano more than; Lagrange remainder; application 目录1. 绪论 1 1.1 综述 1 1.2 泰勒公式的研究背景 2 1.3 泰勒公式的研究意义 2 1.4 泰勒公式的研究目的 2 1.5 本论文所做的工作 3 1.6 本论文的基本思路与采用的
