I just don't get it. I can understand the ideas behind the formulas, and all that, but i can't ever use them right. Now, i don't have a specific question about anything really, i just need to figure out how to think about problems the right way so that i know what to do with them. I just sort of stare at them and write down all the formulas i can think of. Not a great way of doing things. I just don't even know where to begin.
