I once heard a speaker at a conference explain calculus this way. He said that if you are watching a movie, and stop the projector (videotape for you younger folks), you could look at the frames separately. Look at two that are consecutive (side by side) and it is difficult to notice any differences in them. You know there are differences. However, they are so small you cannot easily see them. Now look at two other frames of the movie, but this time choose two that are 10 to 20 frames apart. Is it easier to see the changes from one frame to the other? Now look at the first frame of the movie, and the last one. They are vastly different, are not they? Although it was difficult to see the changes when you were looking at the two consecutive frames, there were changes occurring. That is what calculus does. It looks at change, and expresses it with numbers and equations. -Gail, for the Teacher2Teacher service
