I love the idea of using my past Calc 3 knowledge to linear algebra now, I hope we get into some applications

This class makes me want to take abstract algebra even though unsure if could ever fit that in a schedule without going over 4 years for a bachelor’s…

It is interesting how the inverse of the orthogonal matrix it's transpose

[Elijah_Hoenig]

So would it be fair to consider the orthonormal/vector relationship the "opposite" of a matrix/eigenvector relationship, where orthonormal matrices change direction without changing magnitude while a matrix with its eigenvectors changes magnitude without changing direction.

in 22:50, could that at any chance mean that U(t) = U(-1) ?
