在“圆锥曲线”内容中,为了研究曲线与方程之间之间的各种关系,引进了一些基本概念和数学方法,例如“圆锥曲线”,“曲线的方程”等概念,函数与方程的数学思想、数形结合思想、回归定义等方法,对于这类特定的概念理解不准确,对这些方法的掌握存在某些缺陷,解题时就容易出错． In the content of “conical curve”, in order to study the various relationships between curves and equations, some basic concepts and mathematical methods have been introduced, such as “conical curves”, “curve equations” and other concepts, functions and equations of mathematics Ideas, combined ideas of numbers and shapes, regression definitions, etc., are inaccurate for the understanding of such specific concepts, and there are certain deficiencies in the mastery of these methods, and it is easy to make mistakes when solving problems.
