在近几年的高考试题中,出现了含参数的函数与不等式在某区间上恒成立求参数的范围的压轴题.恒成立问题一直是中学数学的重要内容,它是函数、数列、不等式等内容交汇出的一个较为活跃的知识点,越来越受到高考命题者的青睐。大多数学生处理此类问题时感觉十分困难,无从下手,得分率很低,那么有没
In recent years, college entrance examination questions, there has been a parametric function and inequality constants in the establishment of a range of constants to determine the scope of the parameter axis.The constant problem has always been an important part of secondary school mathematics, it is a function, sequence, inequality, etc. Convergence of content out of a more active knowledge point, more and more subject to college entrance examination proposition of all ages. Most students feel very difficult to handle such problems, they can not get started, their scoring rate is very low, so are they?
