解析几何综合题是高考命题的热点内容之一.这类试题往往以解析几何知识为载体,综合函数、不等式、三角、数列、平面几何等知识,所涉及到的知识点较多,对解题能力考查的层次要求较高,考生在解答时,常常表现为无从下手,或者半途而废.据此笔者认为:解决这一类问题的关键在于:通观全局,局部入 Analytic geometry synthesis problem is one of the hot topics of college entrance examination propositions. Such questions often use analytical geometry knowledge as a carrier, synthesis functions, inequalities, triangles, sequences, plane geometry and other knowledge, more knowledge points involved, and problem solving. The level of competency examination is highly demanding. Candidates often find themselves incapable of starting or half-way in answering. According to this, the author believes that the key to solving this type of problem lies in:
