See our solution for Question 1E from Chapter 1. Quisque eget sagittis purus. Nunc sagittis nisi magna, in mollis lectus ullamcorper in. Sed sodales risus sed arcu efficitur, id rutrum ligula laoreet. Quisque molestie purus sed consequat fermentum. Fusce ut lectus lobortis, viverra sem nec, rhoncus justo. Phasellus malesuada, ipsum ac varius euismod, purus nulla volutpat nunc, eu fermentum odio justo porttitor libero. Quisque viverra arcu nibh, at facilisis tortor ornare non. Etiam id porttitor arcu, ut eleifend nisi. Ut sit amet enim eu lacus egestas tristique eleifend sit amet lectus.

True, by Theorem 4 in Section 1. The columns are all pivot columns if and only if there are no free variables.

As in Exercise 3, row operations are unnecessary. This equation is possible if and only if b is zero. These vectors are also linearly independent as elements of V. This basis would be a spanning set for V with p or fewer vectors, which contradicts the assumption. Theorem 7 guarantees that the set of all five eigenvectors is linearly independent. From Example 6 of Section 1. The exact solution is , —, , —, Then H contains a basis S consisting of n vectors. Perpendicularity in R 2 should be a familiar concept even though orthogonality in R n has not been discussed yet. A larger positive multiple of 8 for x3 makes x2 negative. The remaining variable x2 is free. By definition, the jth column of AIn is Aej, which is simply aj because ej has 1 in the jth position and zeros elsewhere.

See the warning after Theorem 4. The entries in x2 give the approximate distribution of cars on. There are three pivot columns, so the dimension of Col A is 3. See the subsection Addition and Scalar Multiplication. Since x has 3 entries, A has 3 columns. By the Diagonalization Theorem, eigenvectors form the columns of the left factor, and they correspond respectively to the eigenvalues on the diagonal of the middle factor. The matrix in Example 3 is diagonalizable, but it has only 2 distinct eigenvalues. With two pivot positions and only two rows, A has a pivot position in every row.
