Unwrapping sine
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 y value of point C. Trace out one complete revolution of this circle.
2. In the input bar, graph sin(x). What do you notice?
3. Where does the "extra" part of the graph of sine come from ?
