Hi everybody,

Can someone please direct me to a site where they explain well the equations and tween class developed by Robert Penner.Coz when I did research on the net they are just equations with no clear tut like explanations.For someone starting flash its pretty confusing.  
I would like also some examples where they implement these classes.

Thanks in advance
