Physics and Math animated video I would like to start and create math and physics animated video. Do you guys have any suggestions on the software to use? I have a Wacom tablet to draw but I am not sure I want to draw myself or instead to somehow use tools that do stuff like drawing graphs, equations etc..

So any suggestions and ideas will be precious.

P.S. It would be nice to have something that includes the latex features 

P.P.S. Some introductory tutorial would be also useful
GeoGebra Math Apps is an awesome option to do 2-D and 3-D static pictures and animations.

You may do it on-line, or download individual applications into your PC or tablet / smartphone.

It partially supports LaTeX and is for free.
