Transformation of trigonometric functions

TheMathCoach explains how to determine the transformation factors for the trigonometric functions sine and cosine from the graph and from the symbolic expression. The video also covers: How to graph trigonometric functions, How to determine the Amplitude, Period, Phase shift and Vertical shift for a trigonometric functions. There are examples included for each concept, to help clarify it while allowing the viewers to test their new knowledge.

Can also be explained as the magnitude of the difference between the functions extreme values. ► Period: The interval over which the values of a periodic function recur. The trigonometric functions are included in the periodic functions. ► Phase Shift: Also known as the horizontal shift and is the distance the trigonometric function has been moved in the x-direction. ► Vertical Shift: Is the distance the function has been moved in the y-direction.
