Is the quadratic form A = 1 positive definite, negative definite, positive semi-definite, negative semi-definite, or indefinite? (Hint: the matrix is not symmetric, so the theorems by using either the leading principal minors or the eigenvalues do not apply. Write down the explicit form of the quadratic form, then plug in some special values for .)
