在各类考试中,含参数的导数解答题通常都作为压轴题的形式出现.这类考题由于含有参数,难度往往较大,因此,如何处理参数是解题的关键.笔者发现,对于含有参数问题的处理,大都是运用分类讨论的思想或分离参数的思想解答的.事实上,对于含有参数的问题,若能走出定势思维,把注意力转移到如何消去参数上,通过一定的策略,把参数消去,化为不含参数的函数问题,问题往往便迎刃而解.下面,笔者结合个人的教学实践,并
In all kinds of examinations, the derivative questions with the parameters usually appear as the form of the finale questions.This kind of questions, because they contain the parameters, are often more difficult, so how to deal with the parameters is the key to solving the problem.I found that, In fact, for problems with parameters, if we can get out of mindset, we can shift our attention to how to eliminate the parameters, and through certain tactics, To eliminate the parameters into function parameters without parameters, the problem is often solved .In the following, the author combines personal teaching practice, and
