You can create a SURFACE OF REVOLUTION by rotating the graph of ANY FUNCTION about the xAxis, and then explore this surface virtually FROM ANY ANGLE within GeoGebra Augmented Reality!
1st step: Watch the screencast below to see how you can can create such a surface of revolution.
Here, we first graph the function f(x) =3 cos(0.4x+(22/7)),-3.5<=x<=5. We then rotate this function about the xAxis (with a = angle of rotation) using the SURFACE command.
Notice this surface looks like a fish with open mouth.
If interested, you can use this pre-made template that can be found here. Follow the directions on this page to open in the GeoGebra 3D Graphing Calculator on your device.
