WebJan 2, 2024 · A determinant is a real number that can be very useful in mathematics because it has multiple applications, such as calculating area, volume, and other quantities. Here, we will use determinants to reveal whether a matrix is invertible by using the entries of a square matrix to determine whether there is a solution to the system of equations. WebThe determinant of a square matrix is a single number that, among other things, can be related to the area or volume of a region.In particular, the determinant of a matrix reflects how the linear transformation associated with the matrix can scale or reflect objects.Here we sketch three properties of determinants that can be understood in this geometric context.
