"TRUE", give an explanation why it's true; if you answer “FALSE", either give an explar or give an example that demonstrates why it's false. (a) If A is a square matrix with det(A³) = 0, then A is not invertible. (b) For any compatible square matrices A and B, det(A+ B) = det(A) + det(B). (c) In R², the set of vectors with x <0 and y < 0 is a subspace. (d) For a 3 x 3 matrix A, det (rA) = r³ det(A). (e) Every change of basis matrix Pc-B is invertible.

Matrices

‘Matrices’ is the plural form of the word matrix, and it is basically a spreadsheet in the form of a box. In mathematics, various functions can be carried out with matrices. Generally, a matrix comes in the shape of a square or rectangle. The elements are distributed horizontally in the form of rows, and vertically in the form of columns.
