Yeah, I'm going to retool this article. Doesn't ever give the way a matrix is calculated (cases listed are special cases)
The determinant is equal to the product of the eigenvalues of a matrix.
That isn't true, espcecially as in the definition of eigenvalue, you are talking only about real vector spaces. Example:
<math>\begin{pmatrix} 1 & 0 & 0 \\ 0 & 0 & 2 \\ 0 & -2 & 0 \end{pmatrix}</math>.
- Eigenvalues: 1
- Determinant: 4
