一、教材分析1.教材的地位与作用众所周知,解析几何是一门通过建立直角坐标系,用代数方法研究几何对象之间的关系和性质的一门几何学分支。具体的做法是建立直角坐标系,使平面上的点与一个有序实数对一一对应,从而体现了形与数的统一与转化,其内容有着丰富的辩证关系。解析几何主要解决两类基本问题:(1)已知曲线求方程;(2)已知方程求曲线性质。椭圆、双曲线、抛物线统称为圆锥曲线,高中解析几何主要研究它们的性质与应用,是学生掌握解析几何的关键,
First, the textbook analysis 1. The status and role of textbooks As we all know, analytic geometry is a through the establishment of rectangular coordinates, algebraic method to study the relationship between the geometric objects and nature of a branch of geometry. The specific approach is to establish a rectangular coordinate system, so that the point on the plane with a real one-to-one correspondence, which reflects the unity and conversion of form and number, its content is rich in dialectical relationship. Analytic geometry mainly solves two basic types of problems: (1) knowing the curve for the equation; (2) finding the curve for the known equation. Elliptic, hyperbolic, parabolic collectively referred to as the conic, high school analytic geometry mainly study their nature and application, is the key to mastering analytic geometry,
