I would say the best place to learn those things is at www.flashkit.com
Look through a bunch of the flas and you will find a bunch of flas with movement using mathematics and functions. Downlaod the flas and study them.
I have a few flas which work with gravity, inertia, and basic mathematic movment of movies. If you want them, e-mail me at jhogeterp@reduxbooks.com
A lot of this movement used with math is based on videa game programming. Maybe a book in that area would help you.
