# Talk:Determinant

From Conservapedia

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:

.

- Eigenvalues: 1
- Determinant: 4

The other problem:

- Eigenvalues: 2
- Determinant: 8

The *algebraic multiplicity* has to be taken into account, the simple sentence *the determinant is equal to the product of the eigenvalues of a matrix* was misleading.
