抽象函数的对称性问题是高中数学的难点内容之一.这类问题由于其抽象程度高、解答过程灵活,而使学生感到困难.本文给出几个与抽象函数对称性有关的结论,并探讨其在解题中的应用. The problem of symmetry of abstract functions is one of the difficulties in high school mathematics. This type of problem is difficult for students because of its high degree of abstraction and flexible solution process. This paper gives several conclusions about the symmetry of abstract functions and discusses them. Its application in problem solving.
