解析几何综合题解题思路案例分析(国外英文资料) Data worth having From the usual study, accumulation and summary Where there is a problem, there must be some Please also criticize and correct me! Analytic geometry, synthesis problem, solution thought, case analysis Analytic geometry synthesis is one of the hot topics in college entrance examination, and this kind of test questions are usually based on analytic geometry knowledge Synthesis function, inequality, triangle, sequence and so on There are more knowledge involved The ability to solve problems requires a higher level of examination When the examinee answers Often show no way to start Or give up halfway The author thinks that the key to solve this kind of problem is: an overview Local start The overall thinking. That is to master the continuity through the law at the same time Should not only form one problem solving routine Problem solving without analysis Follow your heart Do it there, but take it from the macro Break through from microcosmic In the overall design of the topic and the ideas on effort Constantly overcome the difficulties in solving problems in the journey 1 discriminant - problem solving always show magic Case 1 the known hyperbola Straight line passing point Slope is at that time The upper part of the hyperbola has only one point B to the straight line The value of the trial and the coordinates of the point B at this point Analytic 1: analytic geometry is a discipline that uses algebraic methods to study geometric figures therefore The combination of number and shape is an important method to study the problem of analytic geometry Control sketch Its not difficult to think of passing the point B into parallel lines It must be tangent to the hyperbolic C, and the algebraic form of the tangent is the discriminant of the constructed equation The following solutions can be designed: Problem solving procedure Analysis 2: think from the perspective of algebraic reasoning Distance should be expressed in algebraic form The
