Today in Calculus we learned about integrals and finding the area under a curve. He labled the lower area as U. He eventually had to add the subscript 2 to help indicate what number of integral we were on. Unfortunately he couldn't finish the problem before class ended. I suppose you could say that... *puts on sunglasses* I still haven't found what I'm looking for.
