This lesson is crucial to understanding vectors in this course. Several applications of vectors are discussed, such as finding the equation of a plane that contains three points in space. You will also learn to write a vector matrix, find the determinant, and find inverse matrices. If you have not had a Linear Algebra course, this is a vital lecture. It is a nice refresher either way, however.
thnx for calculation of inverse of matrix.
