Problem Set 15
Q1 - Well done
Q2 - Some gave up on the question.  Well done in most cases
Q3 - Lots of trouble here.  Students didn't really understand what they
should try to do.  Some did get the basis of eigenvectors and showed
characteristic polynomial at Vi equaled zero vector.  But only one
considered a linear combination of the eigenvectors.
Q4 - Done poorly.  Some forgot that it was an if and only if proof.  Most
didn't realize there was two cases or didn't understand what those cases
represented.
Q6 - Well done.  Some trouble with the complex eigenvalue case.  Some gave
general solution as linear combination of two complex eigenvectors.

Problem Set 16
All was well done
