由 ｙ =Ａｓｉｎ(ωｘ +φ0 )到 ｙ =Ａｓｉｎ(ωｘ +φ1 )的图象变换是一种左右平移变换 ,即把ｙ=Ａｓｉｎ(ωｘ +φ0 )图象上所有点向左或向右平移一定单位后得到 ｙ =Ａｓｉｎ(ωｘ +φ1 )的图象 .要进行这一平移变换 ,必须确定平移方向和平移单位 .而确定平移单位和方向通
The image transformation from y = Asin(ωx + φ0) to y = Asin(ωx + φ1) is a left-right translation transform that shifts all points on the y=Asin(ωx + φ0) image to the left or right After a certain unit, the image of y = Asin(ωx + φ1) is obtained. To perform this translation transformation, the translation direction and translation unit must be determined, and the translation unit and direction must be determined.
