WebMina. 6 years ago. What Sal introduced here in this video, is a method that was 'woven' specially for finding inverse of a 2x2 matrix but it comes from a more general formula for determining inverse of any nxn matrix A which is: A⁻¹ = 1/det (A) * adj (A) where adj (A) - adjugate of A - is just the transpose of cofactor matrix Cᵀ. WebIn linear algebra, the transpose of a matrix is an operator which flips a matrix over its diagonal; that is, it switches the row and column indices of the matrix A by producing another matrix, often denoted by A T (among other notations).. The transpose of a matrix was introduced in 1858 by the British mathematician Arthur Cayley. In the case of a …

WebSep 28, 2015 · To get the determinant of a matrix power, det(A^n), also note from the above link that the determinant of a matrix product is the product of the individual determinants. I.e. det(A*A) = det(A)*det(A). So you can extend this to powers and figure out the formula for det(A^n).
