extra credit paper

The rules:
1) Research how vector calculus applies in your chosen discipline of engineering. 
This means actually research it. This is not meant to be easy or something you can just imagine.
2) Write *about* what you discovered in your own words. Two pages double spaced,
2) Cite your references, with a number referring to the references section, in your writing.  This insures that you actually did research something.
3) Document your references, page number and/or section, in a separate reference section.  There should be at least four *distinct* references. At most one should be wikipedia.
4) No plagiarism.  I.e. no copy-pasta, no using other peoples words or ideas without crediting them.

The value to you: UP TO ten points of midterm exam level credit.  You will  have to earn your points, though.
