解析几何是用代数方法研究几何图形,通过建立坐标系,把关于点的几何问题化成关于这些点的代数问题来研究.在解物理题时也经常用到解析几何的知识.求曲线(或直线)的交点坐标在物理上常有应用。在解析几何中,方程组 Analytic geometry is the use of algebraic methods to study geometric shapes. By establishing a coordinate system, the problem of geometry of points is transformed into an algebraic problem concerning these points. The knowledge of analytic geometry is often used to solve physical problems. Finding curves (or straight lines) The intersection coordinates of ) are often used physically. In analytic geometry, equations
