Pseudo-determinant

In linear algebra and statistics, the pseudo-determinant is the product of all non-zero eigenvalues of a square matrix. It coincides with the regular determinant when the matrix is non-singular. (Wikipedia).

det A^T = det A

In this video, I show why det(A^T) = det(A). This shows in particular why you can expand the determinant along any column as well, a fact that is not obvious at all! Enjoy Check out my Determinants Playlist: https://www.youtube.com/playlist?list=PLJb1qAQIrmmBs4zAV3zOo7Ep6o9QlZXi3 Subscri

Characterization of the determinant

In this video, I show why the determinant is so special in math: Namely, it is the only function which is multilinear, alternating, and has the value 1 at the identity matrix. This is a generalization of a previous matrix puzzle for the 2 x 2 case. 2 x 2 case: https://youtu.be/lIMeIC1ZJO8
