The resulting row echelon form will have exactly one nonzero row. If the column vectors of C T are linearly dependent, then the row vectors of C must be linearly dependent. We have worked hard to earn the trust of our customers and we know the value of buying with confidence from experienced sellers that can ensure your buying experience is hassle free. The remaining column vectors satisfy the following dependency relationships.

The answers in this manual supplement those given in the answer key of the textbook. In addition this manual contains the complete solutions to all of the nonroutine exercises in the book.

The questions in each Chapter Test A are to be answered as either true or false. Although the truefalse answers are given in the Answer Section of the textbook, students are required to explain or prove their answers. This manual includes explanations, proofs, and counterexamples for all Chapter Test A questions. The chapter tests labelled B contain workout problems.

The answers to these problems are not given in the Answers to Selected Exercises Section of the textbook, however, they are provided in this manual. Complete solutions are given for all of the nonroutine Chapter Test B exercises.

Consequently they have not been included in this solutions manual.

On the other hand, the text also includes questions related to the computations. The solutions manual does provide the answers to most of these questions. There are some questions for which it is not possible to provide a single answer. For example, aome exercises involve randomly generated matrices. In these cases the answers may depend on the particular random matrices that were generated. Steven J. Leon sleon umassd. Two nonparallel lines intersect in a point.

That point will be the unique solution to the system. Since parallel lines do not intersect, there is no point on both lines and hence no solution to the system. The system must be consistent since 0, 0 is a solution. A linear equation in 3 unknowns represents a plane in three space. If the planes are parallel or one plane is parallel to the line of intersection of the other two, then the solution set will be empty. The three equations could represent the same plane or the three planes could all intersect in a line.

If the three planes intersect in a point then the solution set will contain only that point. A homogeneous linear equation in 3 unknowns corresponds to a plane that passes through the origin in 3-space. Two such equations would correspond to two planes through the origin. If one equation is a multiple of the other, then both represent the same plane through the origin and every point on that plane will be a solution to the system. If one equation is not a multiple of the other, then we have two distinct planes that intersect in a line through the origin.

Every point on the line of intersection will be a solution to the linear system. If the equations represent planes that are parallel, then they do not intersect and hence the system will not have any solutions. Thus if no glucose is produced then there is no reaction. Note the ratios are still 6: There are no other solutions since the echelon form of A is strictly triangular.

Section 3 7 There are many possible choices for A and B. For most pairs of symmetric matrices A and B the product AB will not be symmetric. Section 4 11 Generally the product of two elementary matrices will be a matrix formed from the identity matrix by the performance of two row operations. See Theorem 1.

It follows form Theorem 1. If B is singular, then it follows from Theorem 1. Row operation III can then be used to eliminate all of the entries above the diagonal. Thus U is row equivalent to I and hence is nonsingular.

Row operation II applied to I will just change the values of the diagonal entries. Since A is nonsingular it is row equivalent to I.

Hence there exist elementary matrices E1, E2,. Therefore the reduced row echelon form of A B will be I C. Section 4 13 If A is row equivalent to B then there exist elementary matrices E1, E2,.

If B is row equivalent to A then it follows from the result in Exercise 24 a that B is row equivalent to U. If B is row equivalent to A, then there exist elementary matrices E1, E2,. Since M is nonsingular it is row equivalent to I. Thus there exist elementary matrices E1 , E2,.

Section 5 15 The block multiplication is performed as follows: It is possible to perform both block multiplications.

Let 0 denote the zero vector in Rn. The solution x obtained using the operation will be more accurate and yield the smaller residual vector. By construction B is upper triangular whose diagonal entries are all equal to 1. Thus B is row equivalent to I and hence B is nonsingular. If E1,. Examining the last row of the reduced row echelon form of the augmented matrix A b , we see that the system is inconsistent.

With these values the Leslie population model should predict that the survival period will double but the turtles will still eventually die out.

The statement is false in general. The statement is true since the zero vector will always be a solution.

The statement is true. A matrix A is nonsingular if and only if it is row equivalent to the I the identity matrix. A will be row equivalent to I if and only if its reduced row echelon form is I. The statement is false. An elementary matrix is a matrix that is constructed by performing exactly one elementary row operation on the identity matrix.

The product of two elementary matrices will be a matrix formed by performing two elementary row operations on the identity matrix. The row vectors of A are x1yT , x2yT ,. Note, all of the row vectors are multiples of yT.

Since x and y are nonzero vectors, at least one of these row vectors must be nonzero. The resulting row echelon form will have exactly one nonzero row.

However, if there is more than one solution, then the echelon form of A must involve a free variable. If one equation is a multiple of the other then the equations represent the same plane and any point on the that plane will be a solution to the system.

If the two planes are distinct then they are either parallel or they intersect in a line. If they are parallel they do not intersect, so the system will have no solutions. Geometrically the 2 equations represent planes that both pass through the origin, so if the planes are distinct they must intersect in a line.

Therefore it follows from Theorem 1. If this is done the second row of the augmented matrix will zero out in the elimination process and you will end up with one equation in 2 unknowns. It follows from Theorem 1. In general the product of two symmetric matrices is not necessarily symmetric. If E and F are elementary matrices then they are both nonsingular and their inverses are elementary matrices of the same type.

Chapter Test B 25 Theorem 2. The proof is by induction on n. If E is an elementary matrix of type III formed from the identity matrix by adding c times its ith row to its jth row, then E T will be the elementary matrix of type III formed from the identity matrix by adding c times its jth row to its ith row 9.

We are assuming the entries of A are all real numbers. Thus V will be nonsingular if and only if the three points x1 , x2 , x3 are distinct. Thus AB is nonsingular if and only if A and B are both nonsingular.

To see this look at the cofactor expansion of the B along its last row. Since 1! By the induction hypothesis the calculation of det M1j requires m! Thanks for stopping by!
