We prove several basic facts about singular values in this video. First, we prove that the up to the correct sign, the determinant of a matrix is the product of its singular values. Next, we prove that multiplication a matrix by a unitary matrix will not change the singular values. Finally, we prove that the singular values of a positive definite matrix are the same as the eigenvalues of the matrix.
