解析几何是一门用代数方法研究几何问题的学科,解析几何问题首先是一个几何问题,然后才是代数问题.“代数”是解决几何问题时的重要工具,“几何”才是问题的起点和终点.在解决有关解析几何问题时,首先分析图形特点,挖掘几何特征,尝试用平面几何知识进行解决,这样不仅能体 Analytic geometry is a discipline that uses algebraic methods to study geometry. Geometrical problems are first of all a geometric problem and then algebraic problems. “Algebra” is an important tool for solving geometry problems, and “geometry” is The starting point and the end of the problem.In the resolution of the analytical geometry problems, the first analysis of the characteristics of the graphics, mining geometric features, try to use plane geometry knowledge to solve, so that not only
