complicated formula that is derived from a pattern of multiplication and addition using the numbers in the matrix. When determining the matrix by hand, however, you can use a shortcut method to quickly
The eigenvalues of a matrix are the scalars by which eigenvectors change when some transformation is applied to them. Learn how to find the eigenvalues of 2x2 and 3x3 matrices using the characteristic equation with examples.
How to find the inverse of an elementary matrix? Let A = \begin{bmatrix} 1 & 2 & -4\\ 0 & 1 & 2\\ -1 & 2 & 0 \end{bmatrix},\; C = \begin{bmatrix} 0 & 4 & -4\\ 0 & 1 & 2\\ -1 & 2 & 0 \end{bmatrix}. Find an elementary matrix E such that EA ...
