How to Find the Determinant of a 4x4 Matrix Using Cofactors.
In this video, I demonstrate how to find the determinant of a 4x4 matrix using the method of cofactors. You'll see a complete, step-by-step example that breaks down the process of expanding along a row or column to calculate the determinant of a larger matrix.

2x2 Determinant
3x3 Determinant

What You Will Learn:

How to find the determinant of a 4x4 matrix using cofactor expansion.
A detailed example that walks through the entire calculation process.
How to select rows or columns to simplify the cofactor expansion.
Tips on handling zeros and negative signs effectively during determinant calculation.
A deeper understanding of matrix properties and how determinants apply to linear algebra problems.
This tutorial is perfect for anyone looking to strengthen their skills in linear algebra, particularly those studying determinants of larger matrices. Follow along to master the process of finding determinants with cofactors, and you'll be able to tackle any matrix of size 4x4 or larger.

For a shortcut, using matrix manipulation, get everything to the left of the main diagonal to be 0, and get the right of the main diagonal to be non-zero. Then the answer is simply the product of the main diagonal for any size matrix.

Hi Patrick can please make a video about Assets=Liabilities+Equity

debits and credits

Like accounting videos though not if this corresponds to math.If yoi can if not is is cool.

The rules of accounting math.That would be great
