数列是一类特殊的离散型函数,数列不等式与连续型函数不等式的解题技巧和方法有一定的共性,但数列问题多利用其自身固有的特点来解决,二者解决问题的技巧与方法也大不相同。放缩法是解决数列不等式问题行之有效的主要方法,本文主要针对通项为分式形式的数列不等式证明,提供一些解题方法。 The sequence is a special type of discrete function. The sequence inequalities have certain commonalities with the solution techniques and methods of continuous-type function inequalities. However, the sequence problems are mostly solved by their inherent characteristics. The two techniques and methods for solving the problem Very different. The scaling method is the main method to solve the problem of numerical inequalities. This paper mainly provides some solutions to the numerical inequalities proving that the general term is fractional form.
