Applying Representation

 The interactive feature on this page requires the FLASH 5 player/plugin. If you do not see a Flash feature above, or if it is behaving strangely, you should download the player/plugin from the Macromedia web site. (You are seeing this message because you have scripting disabled in your browser and we could not detect the presence of the Flash 5 player/plugin.) Questions to consider: How do the representations provide a way to model the situation and find relationships within the problem situation? How can connections be made between the diagram for a large Ferris wheel and the development of the cosine equation? How did the situation promote understanding of the combination of two cosine equations? How is the concept of period of a circular function represented by the graph? How is it represented by the animated diagram? Which aspects of the underlying idea are emphasized by each? Make a list of the different representations that were used. Did the sequence make a difference? Why? How would you prepare to use this problem in your classroom, emphasizing the Representation Standard?
