论文部分内容阅读
《解析几何》第一章——直线,包括三大节:一、有向线段、定比分点;二、直线的方程;三、两条直线的位置关系。 本章是在全日制十年制学校初中数学课本《代数》第四册、《几何》第二册的有关内容的基础上编写的。另外,增加了一节选学内容“二元一次不等式表示的区域”。 全章必学内容的教学时数为22课时,选学内容为2课时(仅供参考)。 下面,我们分大节介绍编写的一些想法。 第一大节包括有向线段、两点的距离及定比分点两小书。这一节是解决研究解析几何的工具问题。
“Analytic Geometry,” the first chapter - the straight line, including the three major sections: First, there are directed segments, fixed score points; Second, the equation of the line; Third, the position of the two lines. This chapter is based on the contents of the fourth volume of “Algebra” and the second volume of “Geometry”. In addition, an additional section of the school’s “Region of Binary Inequalities” has been added. The number of teaching hours for the entire chapter must be 22 lessons, and the content for the lesson is 2 hours (for reference only). Below, we introduce some ideas written in the major section. The first section consists of two sections: directed segments, two-point distances, and fixed score points. This section is a tool to solve analytical geometry.
