Determinant and Eigenvalues (optional)

0 points possible (ungraded)

Recall that thedeterminantof a matrix indicates whether it is singular. For 22 matrices, it has the formula

det(acbd)=adbc

but for larger matrices, the formula is more complicated.

What is the determinant of the matrix A=(3 1/2 0 2)?

On the other hand, what is the product of the eigenvalues 1,2 of A? (We already computed this in the previous exercises.)
