symmetric matrix and eigenvalues

Hi,

If I have a symmetric matrix, is the determinant of it equal to the product of the eigenvalues. And is the determinant equal to the sum of the eigenvalues? If so, how would you show a proof?

Thank you

Re: symmetric matrix and eigenvalues

I don't know what the answer is, but it can't be both the sum and the product of the eigenvalues.
