Question

Find an article from a magazine or newspaper that mentions how a rate of change changes – a second derivative. You may look on the Internet, or in any newspaper, magazine, or trade journal. You may not use an example from any math textbook (or any website designed to explain math). I want to see a real-life second derivative!

1. A copy of the article with complete source information. Highlight or write the part of the article that mentions the rate of change.

2. Write a few sentences telling what the “original function” and the rate of change are. Tell the sign of the second derivative.

3. Assign some letters to the variables here. Using the letters/variables you have chosen, write Leibniz notation for both the first and second derivatives. What are the units of the first and second derivative? (I do not expect you to compute anything here.)
