Find an invertible matrix
Web1. you write both matrix and the identity matrix side by side. So what you see is like a 3x6 matrix (first three columns are the matrix and second 3 columns are the identity) 2.Now … WebThere are three ways to know whether a matrix is diagonalizable: A square matrix of order n is diagonalizable if it has n linearly independent eigenvectors, in other words, if these vectors form a basis. That is because matrix P is formed by the eigenvectors of that matrix.

Weba*x + b*y = 0 a*x + b*y = 0 They are the same, so for any x you can choose y = -a/b * x and both equations will hold. This actually holds for any f = n*e too (e and f both equal to zero is just a special case of this general principle). If f ≠ n*e, then there will be no solutions. I hope this helps a bit.
