Homeworks 6 & 7 ready.

Homeworks 6 & 7 have been graded and are available for pick-up today (Tuesday,
17 December) from 2:30 to 3:30 in HH 318 (the adjunct's office) and during the
final exam period on Thursday, 19 December, 5:30 to 7:30 (although you should
try hard to show up during the first hour).

I will not e-mail homework grades.  You can only pick up your own homework; you
cannot pick-up homework for your friends.  Two homework assignments, one from 6
and one from 7, were submitted anonymously (two different people).  If you want
credit for those, show up and identify yourselves.
