How to Find The Determinant of a 4x4 Matrix (Shortcut Method)

In this video I will show you a short and effective way of finding the determinant without using cofactors. This method is easy to understand and for most matrices is actually faster when you are good at row reduction. This method uses the properties of triangular matrices to quickly identify the determinant of a large 4x4 matrix. This video includes a worked example.
