Unwrapping cosine
1. Move point C. The x value of point P represents the arc length (in light blue) and the y value of point P represents the x value of point C. Trace out one complete revolution of this circle.
2. In the input bar, graph cos(x). What do you notice?
3. Where does the "extra" part of the graph of cosine come from ?
