解析几何中要加强平面几何知识的运用曲阜师范大学数学系李喆解析几何是用代数方法来研究几何问题的一门学科，开创了形、数结合的研究方法．但在平时的解析几何教学中师生往往伯重于相关量的数量关系的研究，习惯于代数的推理过程，而忽视了有关形的知识的应用，摒弃了最... The use of geometric knowledge in plane geometry to enhance the use of knowledge of plane geometry Qufu Normal University Department of Mathematics Li Wei Analytic geometry is an algebraic approach to the study of geometric problems in a discipline, and created a combination of form and number of research methods. However, in the usual analytical geometry teaching, teachers and students tend to focus on the study of the quantitative relationship of the relevant quantities, accustomed to the algebraic inference process, and neglect the application of the knowledge of the shape, abandoning the most...
