The discrimination approach and application of concave and convex function Author: Zhu Hongli Supervisor: Xing Baohua Abstract Concave and convex function is one of the important properties in function. It reflects curving direction of the curve on the function image, and it allows you to grasp the curve properties better about the corresponding function. This paper bases on analysis about the concept of convex and concave function, and focuses on exploring the discrimination approach and application of concave and convex function, such as the application in inequality proving and function max/min value, etc. It makes a detailed exposition with relevant examples. Keywords concave and convex derivative inequality application. 歡迎您的光臨,!希望您提出您寶貴的意見,你的意見是我進步的動力。贈語; 如果我們做與不做都會有人笑,如果做不好與做得好還會有人笑,那么我們索性就做得更好,來給人笑吧! 現(xiàn)在你不玩命的學(xué),以后命玩你。我不知道年少輕狂,我只知道勝者為王。不要做金錢、權(quán)利的奴隸;應(yīng)學(xué)會做“金錢、權(quán)利”的主人。什么時候離光明最近?那就是你覺得黑暗太黑的時候。最值得欣賞的風(fēng)景,是自己奮斗的足跡。壓力不是有人比你努力,而是那些比你牛幾倍的人依然比你努力。 參
