Flying Fish and 4-Headed Monster Creations in GeoGebra Augmented Reality
The title (hopefully) is self-explanatory. :)
For the first screencast, this surface was created by rotating the graph of the function about the x-axis. Notice how restricting the domain of the surface equation created the fish. (For help constructing the surface equation for this function, click here.)
For the second screencast, note how using domain restrictions involving absolute value expressions helped create duplicates of surfaces!
