对于三角函数中的平移变换,学生很难理解,主要是“向哪平移,平移多少”很难掌握。下面笔者从一点看整体的思想、从一般看特殊的思想、从转换的思想、从正难则反的思想来理解,总的概括为:探究1:通过图像上一点的变化看整个图像的平移,体现了从特殊看一般,从一点看整体的思想。对于y=sinωx到y=sin(ωx+φ)的平移变换,初学者 For the translation function in trigonometry, it is very difficult for students to understand that it is difficult to grasp how “translation and translation are”. From the point of view, the author looks at the whole idea from a single point of view, from the general view of the special thought, from the thought of conversion and from the idea of ​​being hard to be counter-productive. The general summary is as follows: Inquisition 1: The translation of the entire image , Reflecting the general view from a special point of view from a whole point of view. For y = sinωx to y = sin (ωx + φ) translation transformation, for beginners
