I'm in University Physics, and my prof. just gave us a lecture to make sure we're aware of how to use derivatives and integrals (first year). However, I haven't learned integrals in high school, and all this quick review did was confuse me. Would someone kindly take a few minutes to give me a quick summary of how integrals work (as well as the notation, which looks like greek [and probably is :P])? I know that they are used to calculate the area under a curve given a certain interval. The concept is not the problem, it's the actual application.
