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. Nam consectetur iaculis dui ac tempor. Nulla a nisi nunc. Suspendisse semper mauris pretium, suscipit sapien nec, hendrerit justo.

A is diagonalizable because you know that five linearly independent eigenvectors exist: three in the three-dimensional eigenspace and two in the two-dimensional eigenspace. Parallel notes for Maple, Mathematica, and ssome calculators appear in separate appendices at the end of the Study Guide.

Exercises 19 and 20 provide a natural segue into Section 1. I am convinced, through personal observation and student surveys, that the students who prepare many of these review sheets consistently perform better than other students. The vector u is in the plane spanned by the columns of A if and only if u is a linear combination of the columns of A. A linear dependence relation among v1, v2, v3 may be extended to a linear dependence relation among v1, v2, v3, v4 by placing a zero weight on v4. The command ref reduced echelon form is available, but I recommend postponing that command until Chapter 2. Since A is triangular, its only eigenvalue is obviously 5. The result is a matrix that a student might write next to A as the first stage of row reduction, since there is no need to write a new matrix after each separate row replacement. The order of the factors for Z is crucial. See the paragraph before Example 1. Thus, the two vectors are linearly dependent. The form of A1B1 shows that it, too, is lower triangular. This is impossible when A is invertible by Theorem 5 , so A is not invertible. This is probably faster than setting up a system of 4 equations in 6 unknowns. There are two trials after the initial trial, so we calculate x 2.

See the Study Guide comments on Exercise 7 that illustrate two common student errors. The intermediate step is often not written. There are two trials after the initial trial, so we calculate x 2. True, by the IMT. At some point the students have to assume the responsibility for mastering this material. Theorem 7 guarantees that the set of all five eigenvectors is linearly independent. The sequence of row operations that reduces A to B also reduces C to D. The solution set could be empty! Many students have difficulty with the difference in finding bases for the row space and the column space of a matrix. The order of the factors for X is crucial. See the solution of Example 4. Use the method of Example 2. The correspondence from the list of eight boundary temperatures to the list of four interior temperatures is a linear transformation. Denote the columns of A by a1, a2, a3.
