>Page 247 Property 9 should read

det(**A**) is the product of the
eigenvalues of **A**. We see this as follows:

If l_{1},
l_{2},
..., l_{n}
are the eigenvalues of A, then they are the roots of its

characteristic polynomial. Hence

c(l)
= det(**A** - l**I _{n}**)
= det((-1)( l

Evaluating this polynomial at l
= 0 gives det(**A**) = (-1)^{2n}l_{1}l_{2}
... l_{n}

and so det(**A**) = l_{1}
l_{2}
... l_{n}.

value symbols should be deleted. The display line should be

det(**A**) = l_{1}
