Find an article that refers to a definite integral. It's possible that you will be able to find an explicit mention of a definite integral. Much more likely, though, the definite integral will be implied -- the article will actually be about accumulated change.

You may look on the Internet, or in any newspaper, magazine, or trade journal. Your example must come from a setting outside of calculus class. In particular, you may not use any example from our textbook, any other math textbook or any website designed to explain math, or any other discussion of calculus you find online.

What do you post?

1. A copy of the article with complete source information.

2- few sentences telling what the integrand (the function inside the integral) represents, what the limits of integration are, and what the definite integral represents.

3. Assign some letters to the variables here. Using the letters you have chosen and the notation we have learned, write the definite integral that you have found. Show that the units work properly in your example. I don't expect you to compute anything here.
