Announcements:

• You can find sample first midterms here (solutions), here (solutions) and here (solutions, note that there is a mistake in 3f, the correct particular solution is (1/3,0,1/3) ).
• You can find our first midterm here (commented solutions).
• You can find sample second midterms here (solutions), here (solutions), here (solutions) and here (solutions).
  Please be careful, as for most of the sample midterms the syllabus of the course covered chapter 4 (which we skipped), so there are some topics (polynomials as vector spaces, change of basis matrix, the row space of a matrix) that are in those exams but won't be in ours.
  At the same time some of the questions of the sample first midterms could be on our second midterm (mostly the stuff on determinants and matrix inversion).
• If you'd like some more T/F questions to practice, you can look at exercises 15 (section 2,1), 9 (2.2), 11 (2.3), 21 (2.8), 17 (2.9), 39 (3.1), 27 (3.2), 21 (5.1), 21 (5.2), 21 (5.3).
  The exercises right after these ones are also good for practice, but there are no solutions.
• A paper and another paper on PageRank.
• Our second midterm here (solutions)
• You can find sample finals here (solutions), here (solutions), here (solutions) and here (solutions).
  Again, keep in mind that fall and summer 2013 are closer to our syllabus than s08 and f12. Questions that are not appearing on the exam are denoted by NEX.
