向量和导数的引人为人们研究函数和空间图形提供了新途径。作为一种分析工具,向量和导数必须在深刻理解的基础上才能充分发挥作用,从而促进数学其他方面问题的研究和解决。因此,在日常教学中,教师必须不断吸收和消化新知识,使自身的知识体系得以不断更新和完善,这样教学水平才能不断提高,教学效果才能得到提升。 The introduction of vectors and derivatives provides a new way for people to study functions and spatial graphs. As an analytical tool, vectors and derivatives must be fully understood on the basis of a profound understanding, so as to promote the research and solution of other aspects of mathematics. Therefore, in daily teaching, teachers must constantly absorb and digest new knowledge, so that their own knowledge system can be continuously updated and improved, so that the teaching level can be continuously improved and the teaching effect can be improved.
