在条件不等式的证明中,如何合理正确地运用所给条件,是解决问题的关键,也是一个难点;如果不等式中变元过多,次数过高,就更使入迷茫而无从下手.为此,我们介绍一种方法——调整法,就是先把条件特 In the proof of conditional inequality, how to apply the given condition reasonably and correctly is the key to solve the problem, and it is also a difficult point; if there are too many variables in the inequality and the number of times is too high, it will even make people feel lost without starting. Therefore, We introduce a method - adjustment method, that is
