If you want to do all of the computer plots at the same sitting:
Computer plots will be needed for
9.1: #5d.
9.2: #8, 13.
9.3: #10d.
9.5: #5e.
9.7: #17.

Exercises from Section 9.1 page 494-496: 
  Do these problems: 3,5,14,15,17,20,21.
  To turn in: 5abd, 14, 20, 21 
     [For 20, 21, the answers are in a figure on the next page.  
      You need to show that these answers are correct.  
      Use the figure to check your work.
     Also the hint in #20 says to establish and use p=r1+r2, q=r1*r2.  
     You can just use (without proof).]

Exercises from Section 9.2 page 506-507:
  Do these problems: 1, 7, 8, 10, 13.
  To turn in: 8, 13.

Exercises from Section 9.3 page 516-520:
  Do these problems: 5, 10, 12, 27.
  To turn in: 10, 27.     

Exercises from Section 9.5 page 540-543:
  Do these problems: 5, 9.
  To turn in: 5bce - after drawing for part e, check that the drawing shows the results you derived.

Exercises from Section 9.7 page 563-566:
  Do these problems: 5, 8, 17.
  To turn in: 17 (except the last sentence of d--no comparison needed)

Exercises from Section 9.8 page 573-575:
  Think about problem 7 without actually doing it.  Think about why would they ask this if the plot
  should be the same?  Assuming it will be different, explain in at most a few sentences why that
  makes sense.
