WebWhat 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. WebAbove, we did multiply a (2x2) matrix with a (2x1) matrix (which gave a (2x1) matrix). In fact, the general rule says that in order to perform the multiplication AB, where A is a (mxn) matrix and B a (kxl) matrix, then we must have n = k. The result will be a (mxl) matrix.
