解析几何是高中数学的核心内容,历年高考中一般设计2小1大3个题目.其主要涉及的题型有两个,一是已知曲线属性探求曲线的方程;二是已知曲线方程,研究曲线的性质.解答问题的核心是把几何问题代数化,充分运用逻辑推理、代数变形等来实现解题目标.一、建立坐标系对于一些数学题目,若建立坐标系,则可把问题转化为解析几何问题,根据解析几何知识、 Analytic geometry is the core content of high school mathematics, college entrance examination in the calendar year, the general design of 2 small 1 big three questions. The main topics involved are two, one is known to explore the curve properties of the curve; second known curve equation, Study the nature of the curve.The key to solving the problem is to algebra the geometric problems, make full use of logical reasoning, algebraic deformation, etc. to achieve the problem solving target.First, the establishment of coordinate systemFor some math problems, if the establishment of coordinate system, you can transform the problem To resolve the geometry problem, based on analytic geometry,
