函数y=Asin(wx+φ)的图象变换比较复杂,它包括相位变换、周期变换和振幅变换,其中相位变换是所有变换中的重点和难点,只有掌握好相位变换知识才能正确地解决其他变换问题,本文意在对学习者如何学好这一知识而提出自己的一点见解.
The image transformation of function y=Asin(wx+φ) is more complicated. It includes phase transformation, periodic transformation and amplitude transformation. Phase transformation is the key and difficult point in all transformations. Only by mastering the phase transformation knowledge can we correctly solve other problems. In order to change the problem, this article is intended to present a little insight into how learners learn this knowledge.
