It took me far, far longer to get this ready than I had anticipated it would, but I have now posted the clarifications for homework #7.

You can download a new PDF file of it, on which I have marked the changes.

Except for the change I made to the sentences about Alaska and Texas, the changes are all just clarifications. And, primarily it is just a clarification of Question 2—for Task 4 in particular, I have added two entire pages of notes.

It doesn’t seem worth it for me to copy and paste the entirety of those two pages here to the blog, so if you want to see what I’ve added, just take a look at the PDF file. My intent here was really just clarification, but in clarifying it, I made Task 4 of Question 2 quite a bit easier (and I added a couple of hints to other things as well). You could in principle complete the homework in the form I handed it out on Tuesday, but you’ll find it much easier to work from the new version.

It’s pretty much a rule that every semester there’s at least one homework that turns out to be kind of a disaster. Given that there are only going to be two more opportunities for disaster, I feel relatively confident that homework #7 will be the only one.
