When is Homework Due?

Since this is a TuTh section, the homework due dates are different than those posted for the MWF section. My system is as follows. The homework that is due for the MWF sections on Friday and Monday is due for us on Tuesday, and the homework that is due in the MWF sections on Wednesday is due in our section on Thursday. It's easy -- you just move the date that it would be due in the MWF section forward to the next date that our TuTh section meets. Thus the first homework assignment is Section 1.1 #10,14,20^*,24,26,36^*, which is due Thursday 2/7, and the second is Section 1.2 #6,11,18,20,30,38^*, Section 1.3 #4,14,26^*,34,48,50, which is due Tuesday 2/12.
