[Question about speed] Animation or Math?

[Durnus]

I'm making a game that can be "drawn" two ways. It consists of bubble people, so I don't have to make good graphics. The arm is seperate from the head.

The first way: animation. The arm is an animation that is pointed the same direction as the body. This could be simpler, but the animations might take up too much ram.

The second way (which I prefer): math. Using cosine and sin, I would set the position of the arm relative to the body. Of course, I don't know how much strain these relatively simple operations put on the system.

Now, this game will have many of these bubble figures on the screen at a time, so I want to choose the optimum way. I can guess the second method would be better, but I don't know.

I think you can have tons of sine and cosine operations going at the same time. I have a bunch of objects using a vector movement in my game, and it runs fine. I've always wondered though, are sine and cosine operations faster in something like an extension, rather than in the mmf2 expression evaluator?
