Here are some of the relevant courses I will be taking:

**AS/SC/MATH 1000 3.00 F**

Differential Calculus (Honours Version)

Differential Calculus (Honours Version)

Calendar copy: Axioms for real numbers, limits, continuity and differentiability. This course covers slightly fewer topics than AS/SC/AK/MATH 1300 3.00, but covers them in greater depth. It should be taken by all those planning an Honours degree in Mathematics or a Specialized Honours degree in Statistics.

MATH 1000 aims to develop the students' ability to think and write clearly, logically and precisely, and to read a mathematical text with understanding, and to write proofs.

**AS/SC/MATH 1010 3.00 W**

Integral Calculus (Honours Version)

Integral Calculus (Honours Version)

Calendar copy: Riemann integral, fundamental theorems of calculus, transcendental functions, integration techniques, sequences, series. This course covers fewer topics than AS/SC/AK/ MATH 1310 3.00, but covers them in greater depth. It should be taken by all those planning an Honours degree in Mathematics or a Specialized Honours degree in Statistics.

**AS/SC/AK/MATH 1021 3.00 FW**

Linear Algebra I

Linear Algebra I

(formerly AS/SC/MATH 2021 3.00 — before 2001-2002)

Calendar copy: Linear equations, matrices, Gaussian elimination, determinants and vector spaces. This course covers material similar to that in AS/SC/AK/MATH 2221 3.00 but at a more advanced level. Required in Specialized Honours Statistics and all Applied Mathematics, Mathematics and Mathematics for Commerce programs except the BA Program in Mathematics for Commerce.

After the concepts in logic and set theory, the most fundamental idea in all of mathematics is that of a function. The simplest type of function is a linear function, and linear functions (also called linear transformations) are what linear algebra is about. Thus, linear algebra is mathematically more basic than, for instance, differential calculus, where more complicated functions are approximated locally by linear ones. Apart from underpinning much of mathematics, linear algebra has a vast range of applications — from quantum mechanics (where it is crucial) to computer graphics to business and industry (via statistics and linear programming).

Additional topics: Euclidean n-space, lines and planes, linear transformations from ℝn to ℝm, abstract vector spaces, basis and dimension, rank and nullity of a matrix.

**AS/SC/AK/MATH 1131 3.00 FW**

Introduction to Statistics I

Introduction to Statistics I

Calendar copy: Displaying and describing distributions; relations in categorical data; Simpson's paradox and the need for design; experimental design and sampling design; randomization; probability laws and models; central limit theorem; statistical inference including confidence intervals and tests of significance; matched pairs; simulation.

Testing a new drug, pricing a derivative asset, evaluating the effects of free trade, making sound investment decisions, and predicting who will win the World Series are all activities that have in common the need to make sense out of ambiguous data. The modern discipline of statistics serves as a guide to scientists, policy makers and business managers who must draw inferences or make decisions on the basis of uncertain information.

Topics include collection and analysis of data, graphical methods to represent data, numerical methods for describing univariate data both for samples and population, summarizing bivariate data, random variables and probability distributions, sampling variability and sampling distributions, estimation and testing using a single sample, comparison of two populations.

It is recommended that students have at least one OAC in mathematics or a 12U mathematics course, but the mathematical level of the course will be quite elementary. Although students will be making 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 all the necessary instruction about how to use the statistical computer package chosen by the instructor.

Although this course is recommended for students who wish to major in statistics, the concepts are broadly applicable and it should be interesting to students who do not plan to specialize in statistics.

Calendar copy: 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.

Differential equations have played a central role in mathematics and its applications for the past three hundred years. Their importance in applications stems from the interpretation of the derivative as a rate of change, a familiar example being velocity. Many of the fundamental laws of physical science are best formulated as differential equations. In other areas, too, such as biology and economics, which involve the study of growth and change, such equations are of fundamental importance.

In this course we will study some important types of linear differential equations and their solutions. Topics will include first-order (differential) equations; homogeneous second and higher order equations with constant coefficients; the particular solution of inhomogeneous second-order equations; first-order linear systems, solutions and phase plane; series-form solutions of equations with variable coefficients; solutions by use of Laplace transforms.

Students will use the symbolic computational computer language maple to study the behaviour of differential equations. No prior experience with this language is necessary.

The first class of numerical methods introduced are those for nonlinear equations, i.e., the solution of a single equation in one variable. We then discuss the most basic problem of numerical linear algebra: the solution of a linear system of n equations in n unknowns. We discuss the Gauss algorithm and the concepts of error analysis, condition number and iterative refinement. We then use least squares to solve over determined systems of linear equations. The course emphasizes the development of numerical algorithms, the use of mathematical software, and interpretation of results obtained on some assigned problems.

This course is intended as a thorough introduction to the use of linear models in statistical analysis, for students who have had at least two terms of statistics. We will be focusing on situations where we have one dependent variable and one or more explanatory variables. The material covered will be drawn from the textbook, supplemented by some material from other sources. The emphasis will be on the use of the models in question for helping in the analysis of data, not on theoretical derivations. Tentatively the lectures will cover Chapters 1-12. The focus will be on Chapter 4 to Chapter 12 inclusive. Students will be expected to use available computing resources, primarily William Small Center (formerly PSII) or Gauss Lab. We will mostly present sample programs and solutions using SAS.

Probability Models

Probability Models

Calendar copy: This course introduces the theory and applications of several kinds of probabilistic models, including renewal theory, branching processes, and martingales. Additional topics may include stationary processes, large deviations, or models from the sciences.

Probability theory has been used to describe and analyze many kinds of real-world phenomena. This course will investigate several classes of probability models, including the following:

- Renewal processes are used to model an event that occurs repeatedly at random times, such as the failure of a machine component. The focus of study is on the long-run average behaviour of such processes.

- Branching processes are a class of simple population growth models. One important question is how the distribution of the number of offspring of one parent can be used to predict the probability that the population eventually dies out. Generating functions will be introduced and used to derive results.

- Martingales are models of "fair games". They have been used to study stock market behaviour and are an important theoretical tool for a wide variety of probability problems. Important results include descriptions of your expected gain if your decision of when to quit (e.g. when to sell the stock) is determined by the behaviour of the process itself.
