I'm doing a project on dark matter and I've found some good information but I still haven't found any related mathematical equations.. are there any not to complicated ones i can relate to it??
The most relevant equations would be the derivation of the rotation curve for a galaxy of a given density profile, but the graphical representation of these curves for Baryons only and Baryons + Dark Matter might be a more accessible and equally informative for you. There is a graph and some info on the http://en.wikipedia.org/wiki/Rotation_curves" site, but I'm sure a quick Google search would pull up a fair bit of info as well, once you read this and know what you are looking for.
Using math not terribly more complex than Keplers laws you can calculate how much uniformly distributed, unseen [dark] matter can exist within the confines of our solar system without messing up planetary orbits [Hints: [1] virial theorem; [2] its less than the mass of Jupiter].
