Written Assignment 3 (due at the beginning of class, Wed. 10/19)

For the three problems in 1.7, you need to write a clear and convincing explanation based on the definitions of linear independence, or linear dependence, or nonsingular matrix, etc. The definitions are the tools here!

3.1 – Section 1.7 #48

3.2 – Section 1.7 #50

3.3 – Section 1.7 #52

For these interpolation problems in Section 1.8, set up the equations for the unknowns very clearly. Then you can solve either by hand or by tech.

3.4 – Section 1.8 #2

3.5 – Section 1.8 #6

For these problems in Section 1.9 of computing inverses, you can check your answers with technology, but you should show all the steps in a solution by hand.

3.6 – Section 1.9 #14

3.7 – Section 1.9 #16

3.8 – Section 1.9 #18
