Find all values of a for which the resulting linear system has a no solution, b a unique solution, and c infinitely many solutions. We use the Practical Procedure see p.
Answer each of the following as true or false. You only have to repeatedly use n times Theorem 3. Indeed, by Theorem 3. Justify your answer. Using Theorem 3. One uses now a. Using again Theorem 3. By Theorem 3. Show that if A is singular, then adjA is singular. So adjA is singular. Use the equality given in Theorem 3. Thus adjA is also nonsingular.
Further, the formulas in Theorem 3. Finally, one can write the equalities given in Theorem 3. Supplementary Exercises Bonus : 1 the Proof of Theorem 1.
Show that if A is symmetric, then adjA is also symmetric. Observe that the following procedure gives also Mij : 1 consider the transpose AT ; 2 in AT delete the j-th row and i-th column; 3 transpose the resulting submatrix.
Further, if A is symmetric i. Chapter Test 3. Use the expansion of det A along the second row fourth row, first column and third column are also good choices, having also two zero entries. Compute a 3A. Notice that A is here and above only an alternative nota- tion for det A. Chapter Test 4. Use the formula of the angle p. Use the remark after the definition p. Hence the system has a unique solution. Not requested linear transformations.
Chapter 5 Lines and Planes Page In Section 4. This happens if and only if see Corollary 3. Exercise 5, p. The planes are perpendicular if and only if the corresponding normal vectors are perpendicular, or, if and only if these vectors have the dot product zero.
Chapter 6 Vector Spaces Page Show that: a If S1 is linearly dependent, so is S2. By a , S2 is also linearly dependent, a contradiction. Hence S1 is linearly independent.
