这一章的主要内容包括椭圆、双曲线、抛物线的定义、标准方程、简单几何性质,以及它们在实际生活中的一些应用,重点掌握椭圆、双曲线、抛物线的定义、标准方程以及简单几何性质,并理解椭圆的参数方程,了解圆锥曲线的简单应用.结合所学内容,进一步加强对运动变化和对立统一等观点的认识,进一步体会数形结合的思想,本章也是高考中的重点部分. The main contents of this chapter include the definitions of ellipses, hyperbolas, parabolas, standard equations, simple geometric properties, and their applications in real life, focusing on the definition of ellipses, hyperbolas, parabolas, standard equations, and simple geometric properties. , And understand the parametric equations of the ellipse to understand the simple application of the conic curve. Combining with what we have learned, we will further strengthen our understanding of the viewpoints of movement change and the unity of opposites, and further understand the idea of ​​combining numbers and shapes. This chapter is also a key part of the college entrance examination.
