L1-2. Special Matrix Operations: Permutations, Transpose, Inverse
... Start by noting that if A is mxp, a conformable B must be pxn. Then AT is pxm and BT must be nxp. For there to be a product ATBT, m = n. But A and B are rectangular! 3. Suppose A and B are both nxn symmetric matrices. Is matrix multiplication of A and B commutative? Why or why not? Note: A proof is ...

... are all unit vectors. A vector whose i th element is one and the remaining elements are all zero is called the i th Cartesian unit vector. Let θ denote the angle between y and z. By the law of cosine, y − z2 = y2 + z2 − 2y z cos θ, where the left-hand side is y2 + z2 − 2y z. Thus, th ...

SOLUTIONS TO HOMEWORK #3, MATH 54
... One way I could work around this is to argue that once I row-reduce such a matrix, it will have a row of zeroes, but this kind of argument is quite difficult to state precisely, so I’ll go about it in a different way. Solution. The final answer is: A square lower-triangular matrix is invertible if ...
