不等式的证明是中学数学的一项基本内容 ,证明不等式的方法多种多样 ,但主要的 ,也是基本的方法就是比较法、综合法、分析法、换元法等这么几种 ,当然在运用这些方法的过程中还需要穿插运用一些其它方法 ,如利用一些基本不等式、反证法、放缩法等等 .下面试图通过一些例子来说 The proof of inequality is a basic content of middle school mathematics. There are many ways to prove inequality. However, the main and basic methods are comparative methods, comprehensive methods, analytical methods, and replacement methods, of course. In the process of the method you also need to intersperse and apply some other methods, such as using some basic inequalities, anti-evidence methods, scaling methods, etc. The following tries to use some examples
