高中数学教材的现状是没有“三次函数”这一节,但整个高中数学教学,尤其是高考总复习,又不能回避对三次函数的探讨与研究,因此,我们有必要将其系统整合,编入教材,单独成节,从而更利于教学. The status quo of high school mathematics textbooks is not the “third order function ” section, but the entire high school mathematics teaching, especially the college entrance examination total review, but also can not avoid the discussion and research on the cubic function, so we need to integrate the system, Into the textbook, a separate section, which is more conducive to teaching.
