一、从几年来高考试题谈起解析几何的基本特点是形数结合,是代数(?)三角与几何知识的综合运用.这种研究方法在进一步学习过程中,有着相当广泛的应用.正由于此,按教学大纲规定,它是高中数学的重要基础知识,相应的在历年高考中它不但占有较大的比重,目常用以作为综合 First, from the examination questions in recent years, the basic feature of analytic geometry is the combination of form and number, which is a comprehensive application of algebra (?) trigonometry and geometry knowledge. This research method has a wide range of applications in the further learning process. Therefore, according to the provisions of the syllabus, it is an important basic knowledge of high school mathematics. Correspondingly, it not only occupies a large proportion in the college entrance examinations over the years, but is often used as a comprehensive measure.
