find a real-life mention of a derivative.

1. The source of your quotation: The name of the publication, the date it was published, and where you found it.
2. Quote the sentence or sentences that mention the derivative. If necessary, you can paraphrase material from earlier in the article to give some context for your sentences. Note that the material need not mention the word "derivative" explicitly, but instead may just talk about "change."
3. Identify the derivative, as you did in the previous assignment; include units, and define all your variables.
4. Note any other information you think is interesting about your find. For example, what's the target audience for the periodical, and would they be surprised to know that they were brushing up against calculus? Or, what conclusions did the authors draw with the help of this derivative? Or, why is this topic of particular interest to you?
