Determinant is used to know whether the matrix can be inverted or not, it is useful in analysis and solution of simultaneous linear equations (Cramer’s rule), used in calculus, used to find area of triangles (if coordinates are given) and more.

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 you use simple operations on them to get the identity matrix on your left 3 columns, if you have done this, then the right 3 columns are now the inverse of your matrix. WebIn linear algebra, a defective matrix is a square matrix that does not have a complete basis of eigenvectors, and is therefore not diagonalizable. In particular, an n × n matrix is defective if and only if it does not have n linearly independent eigenvectors. [1]
