Information about the Final Exam:
- The exam will take place at 9:00am on Monday, December 21;
information about the location will be provided by Registrar's Office.
- The questions on the final exam will test students' understanding of
the theory and their ability to solve simple problems (students will
be required to outline key analytic aspects of the solutions to
such problems without any MATLAB programming). The emphasis will be on
understanding basic concepts rather than on details.
- Topics covered after Test #2 will be weighted more heavily and will
account for approximately 62% of the exam score (this is meant to
ensure that all topics covered in the course are weighted approximately
equally in the final grade). However, topics involving complex-plane
methods in error analysis will not be emphasized (recognizing that not
all students have the required prerequisite knowledge).
- Some questions may involve comparison between different sections of
- Students may wish to review the problems from the tests and homework
- All answers must be entered in the booklets provided using permanent
- The exam paper will contain a formula sheet a copy of which is
- Only the McMaster Standard Calculator Casio FX991MS is allowed.
Outline of the Course:
In this course we will study key questions of numerical analysis such
as approximation of functions and approximate differentiation and
integration. We will see how various problems arising in calculus
(both in single and in multiple variables) can be solved
approximately, but with controlled accuracy, using computer
algorithm. In addition to proving theorems about various numerical
methods, we will develop, analyze and implement actual computational
algorithms using MATLAB. We will also show how computational
techniques can be used to illustrate and verify different results of
mathematical analysis. As a highlight of the course, we will introduce
Chebfun which is a MATLAB
toolbox for performing hybrid numerical-symbolic computations with
very high accuracy.

Approximation Practice, SIAM, (2013) (we will focus primarily
on the first chapters, six of which are available free of charge on
the Author's webpage; all
chapters can be generated from the source files provided)
All computational examples will be presented using MATLAB and Chebfun. While MATLAB is available
on the computers in most of the computer labs on the campus, students
are encouraged to purchase The Student
Edition of MATLAB to be able to work with MATLAB at home. Chebfun can be downloaded free of
charge from http://www.chebfun.org/download/.
During the lectures we will provide introduction to Chebfun, however, students are
expected to have already some familiarity with MATLAB.
Advanced Calculus (MATH 2A03 or 2X03) and Introduction to Numerical
Analysis (MATH 2T03).
Assignments: Five homework assignments
will be posted on the course website on the dates indicated in the
table below. The assignments will be due by midnight on Thursday the
following week. Solutions of the assignments should be submitted by
e-mail to math3q03_AT_math_DOT_mcmaster_DOT_ca using the template provided. Late submissions will not be
accepted. Only four best assignments are counted towards the final
mark. The assignments and solutions will be posted on the course
Homework Post & Due Dates (tentative):
There will be two in-class tests planned tentatively on October 8 and November
19. They will last 50 minutes and will cover analytical issues
only (no programming). Only the McMaster standard calculator Casio
fx-991 will be allowed during the tests.
The course will be completed by a 2.5 hour final examination. The
date and location of the final exam will be announced by the
Registrar's office in mid-term. The exam will cover all course
a) Final exam (3 hrs) - 40%
b) Two Test (50 min) - 20% (10% each)
c) Four best homework assignments - 40% (10% each)
Relief for Missed Work:
In the event of an absence for medical or other reasons, students
should review and follow the Academic Regulation in the Undergraduate
Calendar Requests for Relief for Missed Academic Term Work. Please
note these regulations have changed beginning Fall 2015.
You are expected to exhibit honesty and use ethical behaviour in all
aspects of the learning process. Academic credentials you earn are
rooted in principles of honesty and academic integrity.
Academic dishonesty is to knowingly act or fail to act in a way that
results or could result in unearned academic credit or advantage. This
behaviour can result in serious consequences, e.g., the grade of zero
on an assignment, loss of credit with a notation on the transcript
(notation reads: "Grade of F assigned for
academic dishonesty"), and/or suspension or expulsion from the
It is your responsibility to understand what constitutes academic
dishonesty. For information on the various types of academic
dishonesty please refer to the Academic Integrity
Policy,. The following illustrates only three forms of
1) Plagiarism, e.g., the submission of work that is not one's own or for
which other credit has been obtained.
2) Improper collaboration in group work.
3) Copying or using unauthorized aids in tests and examinations.
The instructor and university reserve the right to modify elements of
the course during the term. The university may change the dates and
deadlines for any or all courses in extreme circumstances. If either
type of modification becomes necessary, reasonable notice and
communication with the students will be given with explanation and the
opportunity to comment on changes. It is the responsibility of the
student to check their McMaster email and course websites weekly
during the term and to note any changes.
