If the answer to a problem isn't in the back and the problem wasn't assigned (for credit or specific extra credit — see below), you can do it for extra credit.
I consider a 'section' in this book the material between exercise sets (or from the beginning of a chapter to the first exercise set). For any section, you can also write a one to two page summary of the material focused on telling how you might use it in your life, job, intended career, or another course. The guidelines for the format can be found here (except that yours is only 1-2 pages instead of 2-5).
For any chapter, you can do a computer project or writing project for extra credit. I'll post ideas with the specific extra credit problems below.
A whole section of problems (properly done) will be worth 10 points.
A summary paper for any section is worth 30 points.
The points for computational and writing projects will be determined based on the difficulty of the individual item chosen and the depth of the analysis presented.
Mark all extra credit clearly! If I don't realize it is extra credit, you won't get extra credit for it!
It would probably be best to Group all of your extra credit for a particular chapter into a single set for handing in.
If you've typed it up in LaTeX or *shiver* Word, follow the naming and sending in rules denoted here for your PDF.
If you've hand-written it — why? *sigh* I guess you can hand it in like that...
Please note that you can hand in extra credit problems at any time — up to the final. (That is, you do not have to hand in extra credit just when we are working on a particular chapter. You can hand in Chapter 1 extra credit when we are working on Chapter 4 — or even the other way around!)
