FINAL EXAM INFORMATION
The final exam will be held through the Canvas Quiz and it is an OPEN BOOK exam. You can access the lecture notes and the textbook, but not the external online recourses.
The date and time: 8:30 am - 11 am, on April 14th.
The problems are either true/false questions, multiple-choice questions, AND a few short answer questions.
Although it covers everything we learned throughout this term, the final exam is more focused on the material we learned after the midterm.
FINAL EXAM TOPICS :
Chapter 1: Everything except for I.2.4 and I.2.5
Chapter 2: All of II.1, all of II.2 except II.2.3

Course webpage: http://www.math.ubc.ca/~hajeong/MATH307_2019W2.html
Text book: We will use the following online book as the main text.
Chapter 1 : Linear Equations
Chapter 2 : Subspaces, Bases, and Dimension
Chapter 3 : Orthogonality
Chapter 4 : Eigenvalues and Eigenvectors
Instructor: Halyun Jeong
Office hour: Friday 3-5pm, LSK 300B
Our goal is to cover most of the following topics in the course lecture notes: Interpolation, Finite difference approximations, Formula matrix of a chemical system, Graphs and Networks, Least squres, Fourier series, Fast Fourier Transform, JPEC compression, Power method, Recursion relations, The Anderson tight binding model, Markov chains, Google PageRank.
The course mark will be deteremined based on homeworks(10%), quizzes(10%), a midterm(30%), and a final(50%).
There will be weekly (sometimes bi-weekly) homework assianments. Please hand in your homework when the class starts on due date. The late homework will not be accepted but the lowest marked homework will be dropped in the final grade calculation. Students are encouraged to discuss homework, but should write up their homeworks individually.
If you miss an assesment (homework, quiz, or midterm) for a valid reason -- see UBC Vancouver Senate's Academic Concession Policy V-135, please fill out an academic request form and bring it to your session instructor. In this case, for a missed homework, the weight will be transferred onto the remaining homework assignment. For a missed quiz, the weight will be transferred to the remaining quizzes, If you miss the midterm, the weight will be transferred onto the final exam. Students will be also expected to provide documentation.
Any student who misses an assessment is to present to their instructor a self-declaration form (or relevant documentation if this is not the first time they miss an assessment) within 72 hours of the assessment date or their mark in the missed assesment will be 0. This policy conforms with the UBC Vancouver Senate's Academic Concession Policy V-135 and students are advised to read this policy carefully.
You can also access MATLAB in the math department computer lab which is located in LSK 310. The lab hours are posted here. You may use any free terminal in the labs during these times. Your username and password will be given out in the class. Let me know if you have difficulty in login. You may also use GNU Octave and they are also free. However, the instructor will only be able to answer questions regarding MATLAB.
All exams are closed books and no calculators are allowed.
There will be four in-class quizzes on Jan 22, Feb 5, Mar 18, and Apr 1.
The closed book midterm will be held on Friday February 28, 6:30pm in WESB100.
The final exam date is fixed by UBC (the date/time will be announced soon). Please plan your end-of-term travel carefully according to this date.
