Matrices 12 - shortcut methods for determinants
Previous videos introduced the concepts of a determinant but it was clear that in general these would be rather tedious to compute.
This video introduces rules and shortcuts which allow much faster and easier computation. Here the focus is on the impact on the determinant of scaling rows, columns or all coefficients.
Lectures aimed at engineering undergraduates. Presentation focuses on understanding key prinicples, processes and problem solving rather than mathematical rigour.
