解决高考中文科数学里的含参数的导数应用问题,就是利用导数与函数之间的联系,适当地等价变形构造函数。通过导数这个工具判断出函数的单调性,从而得到参数的取值情况。在近年文科数学高考新课标试卷中,含参数的导数应用题受到命题者的青睐,在高考试卷中经常以压轴题的形式出现,且涉及的知识面广,综合性强,于是该题的得分率很低。很多同学反映说平时没少 The solution to the problem of derivative application involving mathematics in Chinese maths in college entrance examination is to make use of the relation between derivative and function to properly transform the constructor functionally. Through the derivative of this tool to determine the monotonicity of the function, thus getting the value of the parameter. In recent years, liberal arts mathematics college entrance examination of the new curriculum papers, with derivative parameters of the subject by the proponents of the favor, in the college entrance examination papers often appear in the form of pressure axis, and involves a wide range of knowledge, comprehensive, so the problem Scoring rate is low. Many students reflect that usually no less
