New: 9.3.6 Old: 8.3.6. Orthogonal means orthonormal. Determine
the inverse of the orthogonal matrix using the class procedure only.
Find an orthonormal matrix that diagonalizes the matrix
Hint: one eigenvalue is 1.
New: 9.4.16 Old: 8.4.16 Also accurately draw the conic in the
-plane. List the angles of the various axes and
asymptotes.
New: 9.4.18 Old: 8.4.18 Also accurately draw the conic in the
-plane. List the angles of the various axes and
asymptotes. Write out explicitly the relations that compute the
old coordinates from the new ones and vice/versa.

for the matrix of
question 2. What is its shape? How is it oriented?
