解析几何题一直是考生比较头疼的题型,究其原因,主要是考生对于解析几何主要思维方法的把握不准。考生不要走进一看到解析几何就开始联立然后韦达定理的误区,这绝对不是高考解析几何出题的初衷,考生需要从坐标转换的角度、利用圆锥曲线中点与线的关系对求解的问题进行转化,变成基本点的坐标关系,然后求解;或者通过平时在学习以及复习中善于发挥课本的习题的作用,下面结合2009年福建省压轴的解析题,谈谈本人对此题在求解中的一些较为独特的解法.
Analytic geometry has been a headache for candidates more than a problem, the reason is mainly due to the candidates for analytic geometry grasp the main ways of thinking are not allowed. Candidates do not go into the analysis of geometry began to see the United States and then Veda’s error, which is definitely not the original intention of college entrance examination analytic geometry, candidates need to coordinate conversion point of view, the use of the relationship between the midpoint and the cone of the solution to the solution Of the problem into the basic point of the coordinate relationship, and then solve; or through peacetime learning and review in the textbook exercises are good at play, the following combination of 2009 Finale of Fujian analytical questions, to talk about my question on this Solving some of the more unique solution.
