probs 1-5
I strongly encourage working together on HW 15a and turning in one assignment for your
group. For problem 5 I have included a few transitional steps in the row reduction of matrix
B to check your work. Note: Interchanging the first 2 rows is necessary. Some of these
operations can be done in Maple but you need to explore the “mod” command in Maple
help menu. Excel can help for some of the calculations.
