解析几何是中学数学的重点内容之一,它的本质是用代数的知识和方法系统地研究几何问题,通过数形结合思想建立起代数与几何的联系,推动代数与几何的共同发展.纵观近年来的数学高考解答题,对解析几何主要是考查圆锥曲线的知识,这类题型涉及的知识面广、综合性强、创新能力高,成为历年来高考命题的热点和重点.本文仅介绍破解圆锥曲线问题的几种策略,供参考. The essence of analytic geometry is one of the key contents of middle school mathematics. Its essence is to systematically study the geometric problems by means of algebraic knowledge and methods, and to establish the connection between algebra and geometry through the combination of number and form and promote the common development of algebra and geometry. In recent years, mathematics entrance examination answer questions, analytical geometry is mainly to examine the knowledge of conic curves, such questions involves a wide range of knowledge, comprehensive, innovative ability, become the hot topic and focus of the college entrance examination proposition over the years. Several strategies to solve the conic problem for reference.
