WebMore generally, determinants can be used any time there are linear equations and in many ways. They’re central tools in the whole subject of linear algebra. As linear algebra is used throughout mathematics and science, determinants get a lot of use. For instance, in the subject of di erential equations, determinants appear in the solution WebWhen we need to find the inverse of a matrix, the determinant helps. It also tells us important things about the matrix that can be used in linear equations, calculus, etc. The Determinant of a Matrix.
