高考数学解题除了具备扎实的基础知识,掌握基本的数学思想方法外,还强调知识的系统性.学习过程中,学生既要注重知识的横向联系,又要注重知识的纵向联系,要将所学的知识发散成网状,可以随时调取和使用.姨2从求函数f(x)=1+x(1+x2)(x>0)的最小值x(x+1)说起……上例是高考模拟题中的一道解析几何题的一部分,学生在解答的时候感觉无从下手,没有思路.究其原因,主要是题目的切入点没有找到,没有透过表象看到问题的本质.下面给出该题的五种解法.
In addition to having a solid basic knowledge of math problems in college entrance examination, mastering the basic mathematical thinking and methods, but also emphasizing the systematic knowledge of the process of learning, students should pay attention to the horizontal relationship of knowledge, but also pay attention to the vertical relationship of knowledge, Learning knowledge diverges into a mesh that can be retrieved and used at any time. Aunt 2 starts by looking at the minimum x (x + 1) of the function f (x) = 1 + x (1 + x2) ... The above example is a part of the analysis of the college entrance examination simulation questions in the analysis of geometry, students feel unable to start when the answer, no ideas. The reason is mainly the problem did not find the starting point, did not see through the appearance of the nature of the problem Here are five solutions to the problem.
