TITLE: Best tools to teach animations of solids of revolution in a Calculus II class?
QUESTION [5 upvotes]: I would like to show animations of solids of revolutions particularly to those students who are not visualizers. Is there a tool that I (and preferably my students also) can use to create animations? It would be great to know what you use in classroom and how successful it has been.

REPLY [3 votes]: Free software GeoGebra from www.geogebra.org will let you do this. Here is an example
https://www.geogebra.org/m/mzWq2Cet and a video showing the construction of a solid of revolution https://www.youtube.com/watch?v=5wOtyT86Qhw.
Your construction can easily be exported as html and embedded in a website too.
