Homework #8
This homework will not be collected. I strongly recommend doing the Sect. 3.8 problems, to get comfortable with leastsquares approximations. The review problems are a selection of conceptually challenging problems from the book. They don't necessarily represent what the midterm will be like, but they make you think and really test your understanding of the ideas.
Section 3.8 #3, 4, 7, 8, 11, 13, 14
Midterm Review Problems
Section 3.2: #29, 30, 32 Section 3.3: #42, 43, 51, 52 Section 3.5: #34, 36, 40 Conceptual Exercises (p. 268): #1, 2, 10  19
Also, please complete the Week #8 Survey. This one isn't due until Sunday, Nov. 21st at 10pm, since I want you to wait until after the midterm to respond.
Homework #7
due Nov. 12th at 3pm
Starting this week, it is acceptable to use the online matrix calculator (see online resources page), or another calculator, to do row reductions.

Section 3.5 #1  6, 16, 18, 22, 25, 32, 33, 39
