Assignment #6 (Due Friday, 2/9/07)
Posted: Tue Feb 6 11:32:03 MST 2007The following are not assigned, but should be looked into: 1.9: 13-21 on computing inverses via row operations and 1.9: 29-34.

Assignment #4 (Due Tuesday, 1/30/07)
Posted: Fri Jan 26 11:48:41 MST 2007Just computations, no proofs this time. Hand in:If you aren't already matrix fluent, I recommend you work through the odds, 1.5: 1-39 (and 34). But don't hand them in.
- 1.2: 54
- 1.3: 24, 32
- 1.4: 2 (use technology to get the RREF -- show enough explanation that your solution can be replicated)
- 1.5: 16, 20, 48

Rubric for Problem 7, Assignment #1
Posted: Thu Jan 18 12:05:51 MST 2007This rubric shows what I looked for in grading problem 7:When you define a variable, you need to give the name, attribute, and units:
Desideratum Points 1 Variables Defined 10 2 Weight Equation 10 3 Length Equation 10 4 Solve Equations 20 5 Announce (ICPA) 10 Total 60 "Let x = the number of Nickels" rather than "Let x = Nickels";and"Let t = the tomato temperature in degrees fahrenheit" rather than "Let t = Tomatoes".
Assignment #2 (Due Friday, 1/19/07)
Posted: Wed Jan 17 13:48:41 MST 2007
Study Examples Added: Thu Jan 18 14:33:43 MST 2007Become a slick practitioner of EROs and endgame interpretation so's we can have a 15-minute quiz on Friday at the end of class. The directions for the following page-13 problems do not say to solve the systems. But solving the systems completely would be good exercise.
Problem Result 1.1: 27 One solution (integers) 1.1: 28 Many solutions (get a formula in terms of t) 1.1: 29 No solutions 1.1: 30 One solution 1.1: 31 One solution 1.1: 32 One solution 1.1: 33 Where do these three lines cross? 1.1: 34 Many solutions (formula!) 1.3: 4 Many solutions (get a formula in terms of u and v)
Note Experimental Diary Button
Posted: Tue Jan 16 14:34:41 MST 2007Let's try this for a while. If nothing else, it will be good hunting for extra-credit points. Subsequent entries will likely not be so detailed as the day-one entry.
Graders Wanted
Posted: Tue Jan 16 11:31:12 MST 2007Dr Johnson says that she needs graders for classes MATH 025 through MATH 175. If you are interested in this mode of gainful employ, send her a note:johnson@math.boisestate.edu
