If $A$ is a $2 \times 2$ matrix $$A=\left[\begin{array}{ll}a & b \\ c & d\end{array}\right]$$ then $A$ is invertible if and only if $a d-b c \neq 0$ Verify that the inverse of $A$ is $$A^{-1}=\frac{1}{a d-b c}\left[\begin{array}{rr}d & -b \\ -c & a\end{array}\right]$$

The Inverse of a Matrix
Assume that B is a 3x3 matrix with the property that B*B = B. Which of the following statements about the matrix B MUST be true: det(B*B*B*B*B) = det(B) det(B) = 0 None of the above must be true B is invertible

If $A=\left[\begin{array}{cc}0 & -i \\ i & 0\end{array}\right], B=\left[\begin{array}{cc}1 & 0 \\ 0 & -1\end{array}\right]$, then $A B+B A$ is (a) null matrix (b) unit matrix (c) invertible matrix (d) none of these
