大自然是用对称的语言写成的,完美与和谐的对称图形是自然界的本性.大自然似乎巧妙地利用了对称的规律的简单的数学表示,因为大自然的几何对称,根本上就是“数的和谐”.函数是高中数学教学的主线,是高中数学的核心内容,也是整个高中数学的基础.函数的性质是竞赛 Nature is written in a symmetrical language, and perfect and harmonious symmetrical figures are the nature of nature.Naturally, it seems that the simple mathematical representations of the law of symmetry have been skilfully utilized, because the geometric symmetry of nature is fundamentally “ Harmony. ”Function is the main line of high school mathematics teaching, is the core content of high school mathematics, but also the basis of the entire high school mathematics. The nature of the function is competition
