combination of v and w, and the three equations will have no solution. Now I can describe the first part of the book, about linear equations Ax = b. The matrix A has n columns and m rows. Linear algebra moves steadily to n vectors in m-dimensional space. We still want combinations of the columns (in the column space).
EXERCISES AND SOLUTIONS IN LINEAR ALGEBRA 3 also triangular and on the diagonal of [P−1f(T)P] B we have f(ci), where ci is a characteristic value of T. (3) Let c be a characteristic value of T and let W be the space of characteristic vectors associated with the characteristic value c. What is the restriction operator T|W. Solution.

The last equation is 0x+0y =36, which has no solution. 14. b. False. The system x+y =0, x−y =0 is consistent, but x =0=y is the only solution. d. True. If the original system was consistent the final system would also be consistent because each row operation produces a system with the same set of solutions(by Theorem 1.1.1). 16. The ...
4 Solutions to Problem Sets 24 A four-dimensional cube has 24 = 16 corners and 2 · 4 = 8 three-dimensional faces and 24 two-dimensionalfaces and 32 edges. 25 Fact: For any three vectors u,v,w in the plane, some combination cu + dv + ew is the zero vector (beyond the obvious c = d = e = 0). So if there is one combination

4.There are methods for solving linear systems other than Gauss’ method. One often taught in high school is to solve one of the equations for a variable, then substitute the resulting expression into other equations. That step is repeated until there is an equation with only one variable. From that, the rst number in the solution is derived,
