WebMar 3, 2024 · Best answer Since A, B, C are all square matrices of order 2, and CD - AB is well defined, D must be a square matrix of order 2. Let D = [ a b c d] D = [ a b c d] Then, CD - AB = 0 (gives) By equating the corresponding elements of matrices, we get Solving (i) and (ii), we get a = - 191, c = 77 solving (iii) and (iv), we get b = - 110, d = 44.

WebSep 16, 2024 · Solution. First, we have just seen that T(→v) = proj→u(→v) is linear. Therefore by Theorem 5.2.1, we can find a matrix A such that T(→x) = A→x. The columns of the matrix for T are defined above as T(→ei). It follows that T(→ei) = proj→u(→ei) gives the ith column of the desired matrix. WebThe matrices I = A 0, A = A 1, A 2, …, A m 2 must be linearly dependent because the space of m × m matrices has dimension m 2. This means that A is a zero of some polynomial of degree at most m 2. Let n be the smallest degree of a polynomial for which A is a zero.

WebIf a and b are real numbers, then the equation ab = 0 implies that a = 0 or b = 0. That is, the only way a product of real numbers can equal 0 is if at least one of the factors is itself 0. The analogous statement for matrices, however, is not true. For instance, if then Note that even though neither G nor H is a zero matrix, the product GH is.
