I'm going in for my math midterm tomorrow, it's all about directional derivatives, gradients, level surfaces, minimums/maximums/saddle points -- FxxFyy-Fxy^2<0 (hey, I actually know that one!), double integrals, areas, volumes, triple integrals, areas/volumes of polar functions, and all that fun stuff. Hopefully I don't miss any! Now if only I could get off of macrumors and start studying! I don't know how to do any of it yet! I could just start paying attention in class, but that's no fun at all... Peace.
