在探索关于X的方程或不等式中参数t的取值范围时,如果能将所给的方程或不等式变形分离成f(t)与g(x)相等或不等的关系,则可通过确定函数g(x)的值域或最值,列出关于f(t)的不等式,进而求得t的取值范围,这就是分离参数法.用它处理一些含参数问题,既新颖独到又方便简捷.下面举例加以说明. When exploring the range of values ​​of the parameter t in the equation or inequality of X, if the given equation or inequality can be decomposed into the equal or unequal relation of f(t) and g(x), the function can be determined by The value range or the most value of g(x), lists the inequality about f(t), and then obtains the range of values ​​of t. This is the separation parameter method. It is used to deal with some parameters, which is novel, unique, convenient and simple. Here are some examples to illustrate.
