Trash for graphing
Its pretty unintuitive and seems very limited in helping visualize the 3D space
Tested it out
This grapher could use coordinate axes. Its ok, but you can only graph one function at a time and there is no way to distinguish vertical or horizontal translations because of the lack of axes. It just shows you the general shape. Also you have to type in functions like you would on a standard keyboard. An iPad app could easily have buttons tailored for this, like a real graphing calculator. This app is pretty amateur.
