$\frac{dA^{-1}}{dx} = -A^{-1}\frac{dA}{dx}A^{-1}$. 3. Show that a unitary operator $U$ can be written as $U = \frac{1 + iK}{1 - iK}$ where $K$ is a Hermitian operator. Show that one can also write $U = e^{iC}$ where $C$ is a Hermitian operator. If $U = A + iB$. Show that $A$ and $B$ commute. Express these matrices in terms of $C$. You can assume that $e^M = 1 + M + \frac{M^2}{2!} + ...$ where $M$ is an arbitrary matrix. 4. Show that det $(e^A) = e^{Tr(A)}$.
