The main goal of injury and illness prevention programs is to prevent workplace injuries, illnesses and deaths, the suffering these events cause workers, and the financial hardship they cause both workers and employers.
Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts.
One of the original uses of a determinant of a matrix had to do with solving a system of linear equations. Once the determinant of a matrix had been calculated, that number could be used to help quickly compute the solution to a system of equations.
