Light Effects

I've been trying to get a good grasp on the math behind doing good light effects and i've taken triginometry and pre calculous, i'm just not very good at pulling equations out of thin air... Any guides you guys have for doing that or maybe a skeleton forumla?

I'd like to know how to make an object orbit, arc from point a to point b, and oscilate.

Sounded to me like he wanted one of each, since it seems rather impossible to have one object do it all at once.

Yes, i just don't know the mathematical equations to produce motion in those patterns... can anybody offer an example or something?

Um, change the amplitude and wavelength of a sin or cosine wave to your preference. Or even better, learn physics!

I've also taken physics, i just didn't do anything involving equations that were animated by time passing.
