纵观历年高考数学试题,不难发现,试题注重了数学思想方法的考查.在解答某些试题时,要求考生首先要在选择什么样的数学思想方法上加以推敲.同一道试题,采用不同的数学思想方法,其难易程度也不同.若巧妙地选择恰当合理的数学思想方法,可达到化难为易,化繁为简,加快解题速度的目的. 1.演绎数学思想方法的训练与反思例1 已知f(x)=x2/1+x2,那么f(1)+f(2)+f(1/2)+f(3)+f(1/3)+f(4)+f(1/4)=__ 训练本题所考查的知识点很简单,就是函数
Looking at the mathematics questions in college entrance examinations over the years, it is not difficult to find that the examinations focus on the examination of mathematical thinking methods. When answering certain questions, candidates are required to first consider what kind of mathematics and methods they choose. The same questions, using different Mathematical thinking and methods have different degrees of difficulty. If you choose the appropriate and appropriate mathematical thinking methods, you can achieve the goal of making it difficult to make it easy, simplifying and simplifying, and accelerating the speed of problem solving. 1. Training and reflection on the methods and methods of deductive mathematics Example 1 Given that f(x)=x2/1+x2, then f(1)+f(2)+f(1/2)+f(3)+f(1/3)+f(4)+ f(1/4)=__ The knowledge point for training this question is very simple. It is a function.
