**AS/SC/MATH2021.03F Linear Algebra I (Honours Version) **

*1995-95 York Calendar: *Linear
equations, matrices, determinants, vector spaces and inner product
spaces. This course covers material similar to that in AS/SC/AK/MATH2221.03
but at a more advanced level. It is required in Honours Mathematics degrees.

Linear algebra is the study of vectors, matrices and linear transformations. These concepts are used in all areas of mathematics, in all branches of science and in the quantitative aspects of the social sciences. The content of this course is similar to that of MATH2221.03. This course, however, is more theoretical and covers additional topics in linear algebra and its applications. It therefore provides a solid background not only for courses in linear programming and statistics which use linear algebra but also for advanced theoretical mathematics courses such as abstract algebra and functional analysis.

The course begins with concrete topics such as the solution of linear systems of equations by Gauss-Jordan reduction, matrices and determinants. We then proceed to study the more abstract concepts of vector spaces, basis, dimension and inner products.

This is a rigorous mathematics course in which all definitions and proofs are presented in class. In addition, all concepts will be illustrated with examples and reinforced through computational homework problems. Moreover, students are expected to learn to construct proofs as the course progresses. Theoretical homework problems will be assigned, graded and counted towards the final grade. Most exam questions, however, will be computational in nature.

This is an honours course intended primarily for students intending to earn an honours degree in mathematics (other than Honours Mathematics for Commerce). However, all students who meet the prerequisites are welcome.

transformations, eigenvalues, diagonalization, quadratic forms,
Markov chains and isometries. This course covers material similiar to that
in AS/SC/AK/ MATH2222.03 but
at a more advanced level. It is required in
Honours degrees in Mathematics and in Specialized Honours degrees in
Statistics.

This course is a continuation of MATH2021.03. It covers more topics and applications than MATH2222.03 (see above, and "least squares approximations" to the list). The high points of the course are the Cayley--Hamilton Theorem and the orthogonal diagonalization of symmetric matrices.

The text will be the same as for MATH2021.03.

**AS/SC/AK/MATH2221.03FW Linear Algebra with Applications I**

*1995-95 York Calendar: *Systems
of linear equations, linear and affine subspaces of Euclidean
n-space, the Gauss--Jordan algorithm, matrices and matrix algebra,
determinants, vector space concepts for Euclidean n-space (linear dependence
and independence, basis, dimension, etc.), various applications.

Linear algebra is a branch of mathematics which is particularly useful in other fields and in other branches of mathematics. Its frequent application in the engineering and physical sciences rivals that of calculus. Computer scientists and economists have long recognized its relevance to their discipline. Moreover, linear algebra is fundamental in the rapidly increasing quantification that is taking place in the management and social sciences. Finally, ideas of linear algebra are essential to the development of algebra, analysis, probability and statistics, and geometry.

This course and MATH2222.03 (see below) provide a standard full-year introduction to linear algebra. While our focus will not be excessively theoretical, students will be introduced to proofs and expected to develop skills in understanding and applying concepts as well as results. Applications will be left mainly for MATH2222.03.

The text will be Anton and Rorres, Elementary Linear Algebra: Applications Version (7th ed.).

The final grade will be based on term work and a final examination (with possible weights of 60% and 40% respectively).

*Prerequisite:* OAC algebra or any university mathematics course.

*1995-95 York Calendar: *Introduction to differential equations, including a discussion
of the formation of mathematical models for real phenomena; solution
by special techniques; applications; linear equations; solutions in
series; other topics if time permits.

This is a first course in differential equations. The curriculum will include first order ordinary differential equations of various types, including driven linear equations, exact equations, the Bernoulli equation and homogeneous equations. We will also study coupled systems of two first order equations (planar systems) with applications, including the pursuit problem, predator-prey models and other applications. Driven second order equations with constant coefficients will be studied by modeling small oscillations of a pendulum. We will solve these equations by introduction of the Green's kernel via variation of parameters, or by an application of Laplace transforms. Lastly, we will develop series techniques (including the Frobenius method) to find solutions of second order equations with non-constant coefficients.

**AS/SC/AK/MATH2310.03 Calculus of Several Variables with Applications**

*1995-95 York Calendar: *Vector
functions, partial derivatives, gradient, multiple integrals, line
integrals, optimization, applications. Offered in both terms.

This course is the sequel to MATH1300/1310. It is a required course in the ordinary programme in Mathematics, and in certain of the honours programmes in Mathematics for Commerce.

Just as MATH1300/1310 studied the calculus of functions of one variable, this course studies vectors and the calculus of functions of two or three variables. In addition to the above topics, we discuss tangent lines to space curves, tangent planes to surfaces, change of variable in multiple integrals and Green's theorem.

Students wishing to pursue calculus further may follow this course with MATH3010.03.

The central source for the course is the textbook. The lectures will not necessarily cover the same material as the text but will instead complement the material in the text. Reading the text and attending the lectures is essential for success in this course.

The text will be Salas and Hille, *Calculus: One and Several Variables*,
7th ed. (Wiley). (This text was used in 1996-97 in MATH1000/1010
and MATH1300/1310 and other courses; we use nothing in it before
Chapter 11.)

The grade breakdown will be announced later.

*Prerequisite: * One of AS/SC/MATH1010.03, AS/SC/MATH1014.03, AS/SC/AK/MATH1310.03.

**AS/SC/MATH 2320.03F Discrete Mathematical Structures**

*1995-95 York Calendar: *This
course covers the algebraic and combinatorial structures that are
needed in computer science. Topics include set theory, functions, relations,
combinatorics, elements of graph theory, posets, lattices, Boolean algebras,
moniods, groups, morphisms, congruence relations. Intended primarily, but
not exclusively, for students in Computer Science.

Based on consultation with the computer science department, we will emphasize topics which include: Big oh notation, complexity of formulae and algorithms, modular arithmetic, recursive definitions, general inductions, counting principles, recurrence relations and methods for solving them, trees and simple graph theory. The emphasis will include examples arising from algorithms and the ability to carry out analysis, problem solving, proofs and calculations which will be required in upper level courses.

The course does not require previous knowledge of computer science and a student of mathematics should enjoy this introduction to a variety of mathematical topics, many of which are not covered elsewhere.

This course is a prerequisite for COSC3101.03, COSC3402.03, COSC4101.03, COSC4111.03.

The text will probably be
Kenneth Rosen, *Discrete Mathematics and its Applications*
(3rd ed.), McGraw-Hill, 1994.

The grade will probably be based on assignments and quizzes (20%), class tests (40%), and a final exam (40%).

*Prerequisite*:
AS/SC/AK/MATH1090.03 or any 2000-level MATH course without second digit 5, or permission of the Course Coordinator.

**AS/SC/AK/MATH2560.03FW Elementary Statistics I**

*1995-95 York Calendar: *Displaying
and describing distributions, normal distibution. Relationships
between variables, regression and correlation. The need for design,
experimental design and sampling design. Sampling distributions, bias,
variability. Probability models, random variables, probability laws.

Statistics is a collection of methods for observing and analyzing numerical data in order to make sensible decisions about them. In these courses the basic ideas of the analysis of data and of statistical inference will be introduced.

Little mathematical background is required; high school algebra is sufficient. Mathematical proofs will be minimal; reasoning and explanations will be based mostly on intuition, verbal arguments, figures, or numerical examples. Most of the examples will be taken from our daily life; many deal with the behavioural sciences, while others come from business, the life sciences, the physical sciences, and engineering.

Although students will be making some use of the computer to calculate statistics, to create statistical plots, and to obtain a better appreciation of statistical concepts, no previous experience in computing is required. Students will receive in class all the necessary instruction about how to use the statistical computer package Minitab.

Students who have taken MATH2560.03 will normally take MATH2570.03 in the second semester, where they will continue to investigate many basic statistical methods.

The text will be announced later.

The final grade will be based on assignments, class tests and a final examination.

**AS/AK/MATH2580.06 Mathematics of Investment and Actuarial Science**

*1995-95 York Calendar: *Theory
of interest; annuities certain; amortization and sinking funds;
evaluation of bonds and other investments; depreciation, depletion and
capital cost; insurance, including mortality tables, principles of life
annuities, premiums and reserves.

The first four-fifths of the course deal with most of the above topics, with applications to simple and general annuities, perpetuities, loan payments, capital budgeting, and internal rates of return. In the last few weeks of the course, the theory of interest is applied to life annuities and life insurance.

Students will use EXCEL, a spreadsheet available in the micro-computer
laboratory in the Steacie building. This spreadsheet operates on both
the Macintosh
and IBM-compatible platforms. EXCEL will be used to simplify and
illuminate
equation-solving, amortization of loans and mortgages, bond schedules,
depreciation tables, and mortality tables. *No
previous computer experience is assumed.* With the help of notes
and class instruction students will be introduced to the
spreadsheet and to its use in mathematics of finance. Students will receive
individual computer accounts on the ACADLABS server.

Each student will also need a hand-held calculator which has
*power* and *logarithm*
functions. Specifically, it must be able, given values
of $x$ and $y$ , to compute $x^y$ .

The course should be especially interesting to students of business and economics. The emphasis will be on practical problems. Although the mathematical background required is minimal, it is preferred that students will have taken one other mathematics course at university before taking this one.

The required text for the course will be P. Zima and R. Brown,
*Mathematics of Finance*, 4th edition
(McGraw-Hill Ryerson Ltd. 1993).

The manuals for EXCEL will be on reserve at the desk in Steacie Library.

Students who wish a more advanced treatment of the material
should *not* take this course but enrol instead in
MATH 2280.03. In particular, this includes:

- Honours Mathematics for Commerce students. MATH 2280.03 is a required course for this programme.
- Students who are contemplating a career in the actuarial profession. They should take MATH2280.03, followed by MATH 3280.06.

*Prerequisite:* One full university mathematics course.

*Degree credit exclusion:* AS/SC/MATH2280.03.
