摘要
定积分不等式命题的证明涉猎面广且复杂,文中首先以1道考研题为例,从不同角度通过六种不同的证明方法给出了解答;随后列举了七个典型例题,用七种证明方法演示了以定积分不等式为背景的证题思路。
Proof o f integral inequality o f proposition covers widely and complicatedly. This paper firstly takes one test question in graduate student entrance examination as an example, from different angles by six different methods that gives the answer; then enumerates seven typical examples, seven methods to prove to demonstrate the integral inequality for background proof knot thinking.
