Given A=(2003)A = \begin{pmatrix} 2 & 0 \\ 0 & 3 \end{pmatrix}A=(2003), what is A−1A^{-1}A−1?
(0.5000.33)\begin{pmatrix} 0.5 & 0 \\ 0 & 0.33 \end{pmatrix}(0.5000.33)
(2003)\begin{pmatrix} 2 & 0 \\ 0 & 3 \end{pmatrix}(2003)
(0.5000.5)\begin{pmatrix} 0.5 & 0 \\ 0 & 0.5 \end{pmatrix}(0.5000.5)
(3002)\begin{pmatrix} 3 & 0 \\ 0 & 2 \end{pmatrix}(3002)
