This is Part 2 of my course on Linear Algebra. Here, you will learn how to calculate the inverse of a matrix. This is a College Mathematics Course. This is a sneak preview of this lesson. We discuss 3 methods here to find the inverse of a matrix. First, you will learn Gauss' Jordan method to find the inverse of a matrix using elementary operations. You will learn about the normal form of a matrix and rank of a matrix next. Given a matrix A, you will learn how to find 2 matrices P and Q, so that PAQ is the identity matrix. The lesson concludes with Cramer's Rule which teaches you how to find the inverse of a matrix using determinants.
