Final Exam  Thursday 12/6 at 8 AM in lecture room (Center 114)
Q:  What are your office hours for finals week?
A:  Mon 10:00 - 12:30 (I'll stay later if people are around.)
      Tues 10:00 - 12:30 (I'll stay later if people are around.) Math 184A students have priority.
      Wed 12-2 (I'll stay later if people are around.)  Math 15B students have priority.
      Matt Cecil:  Mon 1:00 - 3:00
Q:  What material is covered?
A:  See the note below.
Q:  How long is the final?
A:  I expect it to be about twice as long as the hour exam.
Q:  What are we allowed to bring?
A:  The exam is closed book and NO CALCULATORS are allowed.
You may bring two pages of notes (both sides of page).  They can be handwritten, typed, xeroxed, cut and pasted, or any combination.
Q:  What about all the theorems and definitions we've had?
A:  You are expected to be able to use the concepts in the definitions and the results in the theorems, but you do not need to be able to quote them.
Q:  Section GT-4 has two long theorems.  They'll take a lot of space on my notes.
A:  The material in Theorem 7 is "common sense" if you understand big-oh and Theta notation, so you may not need to write out the whole theorem in your notes.  Theorem 8 (Master Theorem for Recursions) will be provided on the exam if it is needed.
Material for the Final Exam
The exam is cumulative, but I expect it will emphasize material since the hour exam.  You are responsible for all the units; however, certain material was omitted.  Here is a list of omitted material by section.
CL-4: Example 33
Fn-4: Correlation, Tchebycheff's Inequality, Example 23, Example 26 to end of section
DT-1: Permutations     DT-4: Example 27 to end of section
GT-1: Random Graphs     GT:-2: Definitions of trail, walk, circuit; Example 11 to end of section
