中文摘要:有很大一部分函數(shù)雖然可積,但是原函數(shù)卻不能用初等函數(shù)的有限形式表示出來,或者是被積函數(shù)沒有明確給出只知道它的結(jié)構(gòu)或某些性質(zhì),對于這類函數(shù)要求對其進行積分值的估計,這在數(shù)學(xué)分析的學(xué)習(xí)以及考研中占有很重要的地位。本文主要通過結(jié)合具體的例子探討積分值估計的幾種思路方法,給出了一般積分值估計的方法技巧以及利用積分值估計解決一些問題。 關(guān)鍵詞:積分;估計;方法
Abstract:Although a great majority of function can be integrated, original function cannot be shown in a limited form of elementary function, or the integrand is not definitely provided value of such function character. Estimating for the integral value of such function holds a great significant position in the study of Mathematical analysis and exams for postgraduate schools. This article, providing the general methods and skills of estimating the integral value and using the integral value to figure out some problems, discusses several methods of estimating the integral value mainly on basis of some specific cases. Key Words:Integral; Estimate; Method
對于大部分的函數(shù)雖然可積,但是原函數(shù)卻不能用初等函數(shù)的有限形式表示出來,或者是被積函數(shù)沒有明確給出只知道它的結(jié)構(gòu)或某些性質(zhì),這類函數(shù)占絕大多數(shù),對于這些函數(shù)的積分值問題在數(shù)學(xué)分析以及實際應(yīng)用中占有很重的地位,因此下文主要結(jié)合例題歸納這類函數(shù)積分值估計的方法。
