基本不等式不仅是高中数学课程的重要内容,而且也是近几年高考的热点内容;同时,基本不等式作为一种解题的重要工具,与其他数学知识易于交汇,所以,它越来越受各种高中数学考试命题者的青睐;但在应用基本不等式解决问题时,常常需要配合一定的变形与转化技巧,既有难度又较为灵活.就以上问题,笔者在平时的教学与解题中总结与归纳了几条技巧,以飨读者.
Basic inequality is not only an important part of high school mathematics curriculum, but also a hot spot in college entrance examination in recent years. At the same time, basic inequality, as an important tool for solving problems, is easy to meet with other mathematical knowledge. Therefore, High school mathematics test proponents of all ages; but in the application of basic inequalities to solve the problem, often need to meet certain deformation and transformation skills, both difficult and more flexible.To the above problems, the author summarizes and induces in the usual teaching and problem solving A few tips to readers.
