笔者对数学通讯2013年11、12期中《谈一道数学联赛题的数学教育意义》一文的一些观点不太赞成,希望借此平台汇百家之长,谈谈自己的几点认识.文中对一道数学题给出了几种解法后,阐明一些数学方法,笔者认为这几种解法有如下问题:(1)方法都很复杂;(2)方法不适合高中生掌握;(3)几种方法都很容易漏解.例如第一种解法利用柯西不等式,有从答案拼凑的嫌疑;第二种解法出现反三角函数,有超纲嫌疑;第三种方法更是将简
I do not agree with some of the views of “Communication on the Mathematic Education Mathematica of Mathematical League” in the 11th and 12th Issues of Mathematics Communication in 2013. I hope to take this platform together to talk about some points of my own understanding. Mathematical problems given several solutions, to clarify some mathematical methods, I think these types of solutions have the following problems: (1) the methods are complex; (2) the method is not suitable for high school students to master; (3) For example, the first solution using Cauchy inequality, there is suspicion of patchwork from the answer; the second solution appears anti-trigonometric function, there is overstretch suspect; the third method is to Jane
