.

This happens if and only if the columns of A are linearly independent. Since D is in echelon form, it shows that C has a pivot position in each row. See Example 6 in Section 4.

Account Options Ieiet. Linear Algebra and Its Applications. David C. Lay , Steven R. Lay , Judith McDonald. This Fifth Edition provides substantial support both for teaching and for using technology in the course. As before, the text provides a modern elementary introduction to linear algebra and a broad selection of interesting applications. The material is accessible to students with the maturity that should come from successful completion of two semesters of college-level mathematics, usually calculus. The main goal of the text is to help students master the basic concepts and skills they will use later in their careers. The topics here follow the recommendations of the Linear Algebra Curriculum Study Group, which were based on a careful investigation of the real needs of the students and a consensus among professionals in many disciplines that use linear algebra.

The range is the set of all linear combinations of the columns of A. True, by Theorem 3. Note: The Study Guide suggests that students ask their instructor about how many details to include in their proofs. Every column in the augmented matrix except the rightmost column is a pivot column, and the rightmost column is not a pivot column. Then there are no free variables in this equation, and so A has n pivot columns. The work in Exercise 17 shows that statement d in Theorem 4 is false. The vector c is —1. The plus signs should be just spaces between columns. Take some other value for pS, say million dollars. If T is one-to-one, then the columns of A are linearly independent by Theoerm 12 in Section 1. Exercise 44 is fairly difficult for my students.

If you discussed partitioned matrices in Section 2. By Theorem 12 in Section 1. Find the general traffic pattern in the freeway network shown in the figure. See the Study Guide comments on Exercise 7 that illustrate two common student errors. By Theorem 6 in Section 2. Since MATLAB computes numbers accurately to 16 decimal places, the entries in the computed value of x should be accurate to at least 11 digits. So B is diagonalizable. Here c1, c2, c3, and c4 are suitable scalars. The solution set consists of all possible solutions. Let the columns of E be denoted by c1 , … , c m.
