在数学竞赛中的分式不等式的证明,往往带有一定的技巧性,因此证明过程常常会用到著名的不等式.这种做法忽视了证明不等式基本的方法即作差法,这里我们通过作差法来简易的证明数学竞赛中的分式不等式.
The proof of fractional inequalities in mathematical competitions often has some skill, so the proof process often uses famous inequalities. This practice ignores the basic method of proving inequalities as the difference method. Here we pass the difference method. Law to easily prove fractional inequalities in mathematics competitions.
