Finding Inverse of a Matrix using Determinants Directly

In this video, Inverse of a matrix using Determinants is explained using examples. Minor, Cofactors, Transpose of a Matrix and Adjoint of a matrix is explained. A direct method along with the usual method is also explained for finding inverse.

Notes, Practice problems and solutions can be found on my website
