Thursday HW!

Tonight please complete questions 1,2, 4, and 5 on the "Solving Multivariable Systems" worksheet provided in class (or below). For questions 2, 4, and 5 use your graphing calculator and matrices to solve the systems!

And if you're feeling ambitious here's your weekend homework (from the problem set I gave you yesterday)--more practice solving systems with matrices! USE YOUR GRAPHING CALCULATOR AND MATRICES TO SOLVE (ignore the Gaussian directions). 

Section 8.1 (page 582): 59, 65, 71 (use rref and the augmented matrix to solve)
Section 8.3 (page 608): 47, 61, 63 (use "A inverse B" with the coefficient and solution matrix to solve)

You will also have a question like 82 or 85 in section 8.1 on  next week's test so it's a good idea to look at these! There will also be a question or two like 67/69/71 in section 8.3! If you do/try any of these with your homework and show me the work on Monday you can get an extra credit homework grade!

(Extra Credit HW: section 8.1 #85, section 8.3 #67, 69, 71).
