Do on your own: 

	15.1 all core problems
	15.2 all core problems
	15.3 all core problems (note: core problem #66 will be turned in)


Hand in: 

	There will be no problems to hand in this week.  Next
	week's homework will include Problem #66 on 15.3, on
	some material I didn't finish covering as of FRI 10/5. 
	This will make next week's homework a little longer,
	but I thought many of you could use a break during the
	week of the midterm.
