恒成立问题是高中数学的重要组成部分,它主要涉及一次函数、二次函数、复合函数以及导数等多个知识点,重点考查学生的综合解题能力。然而,正是由于这个数学知识点涉及多方面的知识,综合性强,使得许多学生在解题时无从下手,从而使恒成立问题成为高中阶段数学学习的一个重难点。那么,如何让学生快速掌握解答此类问题的技巧和方 Constantly established problem is an important part of high school mathematics, which mainly involves a number of knowledge points, such as a function, quadratic function, complex function and derivative, focusing on students’ ability to comprehensive problem solving. However, it is precisely because of this mathematical knowledge point involves a wide range of knowledge, comprehensive, making many students can not start solving problems, so that the problem of constant formation of high school math learning a major difficulty. So, how to make students quickly master the skills and methods to solve such problems
