Pages 212-214, \# 2, 3, 5, 7, 14 (but do not bother
to compare the result in 14 with Theorem 4.3.2).
\item
Write a matlab program to solve the problem
\[  \begin{array}{cccc}
       \max & x_1 + x_2  \\
\mbox{ subject to~} &   x_1^2 + x_2^2 -1 &= &0
     \end{array}
\]
Use the penalty function method.
(Compare with the matlab toolkit.)
