| Abstract: | This article makes a systematic analysis of the definition,judgment and properties of convex function, and points out the convexity of elementary function. And by using the convexity of elementary function if also demonstrates the arithmetic mean and geometric mean inequality and a group of triangular inequality which are aften found in the middle school. |
