Linear Algebra: Ideas and Applications, Fourth Edition provides a unified introduction to linear algebra while reinforcing and emphasizing a conceptual and hands-on understanding of the essential ideas. The same may be proven true for columns by applying the above result to AT and using Theorem 5. Notice that the same argument will not work in general for AAT , since AT has more rows than columns, so its columns are not automatically linearly dependent.

Note that this is the condition number, which is used in Section 2. As before the. Notes: This section features several independent topics from which to choose. The geometric interpretation of the determinant Theorem 10 provides the key to changes of variables in multiple integrals. We compute 1. We compute 2. We compute 3. We compute 4. We compute 8. We compute Each cofactor of A is an integer since it is a sum of products of entries in A. Hence all entries in adj A will be integers. First translate one vertex to the origin.

For example, subtract —1, 0 from each vertex to get a new parallelogram with vertices 0, 0 , 1, 5 , 2, —4 , and 3, 1. For example, subtract 0, —2 from each vertex to get a new parallelogram with vertices 0, 0 , 6, 1 , —3, 3 , and 3, 4.

This will happen if and only if one of the columns is a linear combination of the others; that is, if one of the vectors is in the plane spanned by the other two vectors. Alternatively, one may compute the vectors that determine the image, namely, the columns of A [b1.

The determinant of this matrix is —24, so the area of the image is The determinant of this matrix is 20, so the area of the image is The area of the triangle will be one half of the area of the parallelogram determined by v1 and v 2. Translate R to a new triangle of equal area by subtracting x3 , y3 from each vertex. By Exercise 29, the area of the triangle will be. By part a. The inv A command requires only about 0.

The columns of A are linearly dependent. See Exercise 30 in Section 3. See Theorem 3 b. See Theorem 3 c.
