论文部分内容阅读
今年高考已确定不考这部分内容,但考虑今后教学的需要,特刊出供参考。本章教学内容,只是积分学里最基本的知识。总的教学要求是比较低的。在复习中不要增加例、习题的难度。更不能扩充内容。下面谈几点意见,供复习时参考。一、明确复习要求通过复习,进一步理解基本概念,熟练基本方法,会简单应用。基本概念包括原函数、不定积分,定积分的概念。基本方法包括直接积分法、换元积分法、分部积分法。其中以直接积分法为主,后两种方法只要求能处理一些较简单的习题即可。如课本所要求的习题的难度。简单应用包括会解决一些简单平面图形的面积及其旋转体的体积计算问题。
This year’s college entrance examination has decided not to examine this part of the content, but considering the need for future teaching, the special issue is for reference. The teaching content of this chapter is just the most basic knowledge in integra- tion. The total teaching requirement is relatively low. Do not increase the difficulty of examples and exercises in the review. Can not expand the content. Here are a few suggestions for reference when reviewing. First, a clear review of the requirements through review, to further understand the basic concepts, skilled basic methods, will be simple to apply. The basic concepts include the original function, indefinite integral, and the concept of definite integral. The basic methods include direct integration method, replacement element integration method, and partial integration method. Among them, the direct integration method is the main method, and the latter two methods can only handle some simpler exercises. Such as the difficulty of the exercises required by the textbook. Simple applications include solving problems with the area of some simple planar graphics and volume calculations for rotating bodies.
