Math 442 Exams

Midterm, Tuesday 9th February 14.00-15.30, Location  WESB 201

The midterm will cover chapters  1, 2, part of 4. (Homeworks  1-5.) It is a closed-book exam: no books, notes, or calculators may be used. Bring your student id and, if you like, coloured pens/pencils.

The topics covered are:  Konigsburg bridge problem,  Knight's tour, dice walks, sprouts, parse trees, alkanes, people at a party, complement, isomorphic, subgraphs, matrix representations, types of graphs, Eulerian graphs, Hamiltonian graphs and applications, planarity, contractible, homeomorphic.

Extended office hours: Thursday February 4th **5-6.30pm**. I will also be on email during regular work hours Monday February 8th (when UBC is closed).

Practice questions: 1.4, 1.5, 1.20, 2.20, 2.33, 4.4 (justify your answer). Answers are in the back of the book.

Some study hints:

  1. This is a Math Majors course, which means the exam will be about 50% proofs 50% calculation. You will be expected to prove results like on the homework, or in class.
  2. To study efficiently make sure you know the definitions, the algorithms/methods for computing things, the formulas for things, and results/proof methods we use most often. Perhaps write them in your own words, or explain them to a friend.
  3. Do the lecture examples, practice questions and old homeworks again without looking at the answers.
  4. Go through the posted homework solutions to gain another point of view on solving the questions.
  5. In the exam: If you get stuck on a problem in the exam then write down relevant definitions accurately. This will help to inspire you and pick up points for working. If you use a result from class say "From the result in class..." then state the result so the grader knows this isn't made up.

Final exam, Friday 22nd April 15.30-18.00, Location LSK 201

The final will cover the whole course. (Homeworks 1-12.) It is a closed-book exam: no books, notes, or calculators may be used. Bring your student id and, if you like, coloured pens/pencils.

Office hours: Wednesday April 20th 2-4pm.

Practice questions: 1.37, 1.48, 2.15, 2.36, 2.42, 3.9, 4.26, 5.7, 5.9, 6.20. Answers are in the back of the book. Plus find the longest distance and path from A to L in Figure 2.37. Answer is Figure 2.38.
