It's called a differential equation. They are used for finding the area of something odd. Not a box, but like how much water is in a lake or how much area a mountian takes up. Stuff like that. There are many applications. I don't use them in my daily job... All those symbols mean something, too, those are what I would have to refresh my memory on.
