所谓含参数不等式,就是指除含未知数之外还含有参数的不等式.此类不等式,往往因参数的取值范围不同,解集也不同.因此,学生掌握含参数不等式的解法和形成解决参数问题的正确思维习惯是突破解含参数不等式的关键.我认为,解含参数不等式时,要先把参数作为常数看 The so-called inequality with parameters means that in addition to the unknowns also contains the parameters of the inequalities such inequalities, often due to different values ​​of the parameters, the solution set is also different, therefore, students master the solution with parameter inequalities and the formation of parameters to solve the problem The correct way of thinking is to break through the key to solving a parametric inequality, and I think that when we solve a parametric inequality, we must first consider the parameter as a constant
