The answers to these questions must be hand written on paper and
all work must be shown to receive full credit.
1. (10) Find the eigenvalues of the matrix below.
2. (15) Let V be the vector space of smooth (i.e. infinitely
differentiable) functions f(x) that map the real
numbers into the real numbers. The second derivative
is then a linear operator that maps V into V.
What are the eigenfunctions of the second derivative operator and
what are the corresponding eigenvalues?
3. Let L be the linear transformation L: given
by
A. (6) Write L as a matrix M in the standard basis
and find the eigenvalues of L.
B. (15) Find the eigenvectors of L in the standard basis.
C. (3) Find the change of basis matrix P to convert to the
basis where L is diagonal.
D. (3) Calculate A = MP.
E. (3) Calculate B = P-1A.
Is B a diagonal matrix with entries equal to the eigenvalues
of L?
F. (3) Calculate the dot product of your two eigenvectors.
