Based on feedback from Wednesday night's help session, it looks like I underestimated the time necessary to complete the class activity (in true professorial fashion). I forgot that problems 6 and 7 required derivations and that many of you have yet to learn LaTeX, and that problem 8 is nontrivial.
Here's the new plan:
Turn in problems 1-5 at the beginning of class Friday. We'll then spend Friday's class talking about LaTeX and working on fitting lines.
