Section \#11.1.5

Change the hint in Exercise \# 2 to the following: 

Show that a matrix $x \in \SL(2,C)$  is semisimple if and only if either
$\tr(x)^2 \neq 4$ or else $x = \pm I$


In Exercise \#4 add the condition that $G$ be connected.  (The assertion
is obviously false otherwise, as shown by taking $G$ to be any finite
noncommutative group and $H$ the trivial group.)
