Solutions

I just posted a bunch of solutions:

1. HW 4 solution, with brain burner shown.
2. Quiz 1 solutions: versions A (white version), B (pink), C(yellow) and D(green). Each version was some variation of handling a half-parabola. Look in the Exam blurbs folder on the home page.
   

I wrote a few variations on the solution of each version. That being the case, it would probably be helpful for everyone to view all solutions, and you could learn something maybe.
