数列不等式的证明问题,近几年来在高考试卷中频频出现,其证明与普通的不等式证明往往有所不同.从本质上讲,数列也是一种函数,所以,我们不妨从函数的角度去寻求这一类问题的解决办法.本文拟从函数最值的角度来尝试证明一些稍为复杂的数列不等式问题,现举例说明如下:例1已知等比 The problem of proof of series inequalities has frequently appeared in the examination papers in recent years. The proofs of the series are often different from ordinary inequality proofs. Essentially, the series is also a function. Therefore, we may seek this from the perspective of functions. A solution to this type of problem. This article attempts to prove some slightly more complicated series inequality problems from the perspective of the function’s maximum value. Here are examples of the following: Example 1 Known ratios
