Talk:Determinant

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. FrankC aka ComedyFan 08:49, 5 May 2010 (EDT)
