In this lesson, we will learn how to find the determinant of any square matrix (n x n) matrix. We will start with the easiest scenario, which is finding the determinant of a 2 x 2 matrix. We will then move on to learning how to use Laplace expansion or cofactor expansion to find the determinant of any n x n matrix. We will then show an excellent shortcut that works quickly for finding the determinant of any 3 x 3 matrix.
