MATH 2084H[284H] 
Recreational Mathematics
 Not offered 20092010 
Description:
This is a generalinterest
course about topics in mathematics that are studied for fun. These
topics include magic squares, logic puzzles, toys and tricks with
mathematical content, polygonal dissections and tiling problems, etc.
These topics will be especially interesting for anyone
who wants to become a math teacher, and will also appeal to nonmathematicians who have
a casual interest in math (e.g. geometric puzzle aficionados, readers
of Martin Gardner's ``Mathematical Games'' and similar columns in
Scientific American, etc.). Some possible topics include:
 Magic squares
 History.
 Algorithms for generating magic squares.
 Tricks for modifying magic squares to create new ones.
 Magic squares with additional properties.
 Logic problems and puzzles
 Deductions involving logical alternatives.
 Puzzles and paradoxes involving selfreferences, including:
 The lady or the tiger.
 The unexpected hanging.
 Dissections
 Cutting up polygons into pieces and reassembling them into other polygons.
 When can a polygon be dissected into another polygon?
 What happens with nonpolygonal shapes?
 What happens if pieces are ``cut'' in more complex ways?
 Tilings
 What combinations of tiles can be used to cover a floor?
 Periodic and nonperiodic tilings.
 Connections between dissections and tilings.
 Polyominoes
 What shapes can be created with given sets of polyominoes?
 Tilings using polyominoes.
 Reptiles (polyominoes which can be tiled by smaller copies of
themselves).
 Extensions of polyominoes to three dimensions, e.g. the Soma cube.
 Map colouring
 The general FourColour Theorem.
 The TwoColour Theorem for a map created by drawing (possibly overlapping)
circles. Investigate how far this theorem can be extended.
 Arithmetic tricks
 Puzzles based on tables for arithmetic operations.

Synopsis::
Analytical and graphical solutions are studied for firstorder,
higherorder and systems of firstorder equations. Applications are shown by
linear and nonlinear Mathematical models in Physics, Biology and other
areas. Laplace transform and its applications are also introduced.
(Time permitting, power series solutions and/or numerical methods may
also be covered.)

A twodimensional vector field determines a flow in the plane.

Overview: Ordinary differential equations (ODEs) model physical systems which evolve
continuously in time. For example, suppose the state of the system is
described by a single variable $x(t)$, and satisfies the equation:
d x(t) 
  =  x(t). 
d t 
If $x(0)=5$, then the unique solution to this equation is the curve
$x(t)\; =\; 5\; et$. This curve starts at
$5$, and asymptotically approaches $0$. We say that $0$ is an
equilibrium state for the system.
Suppose the state of the system at time $t$ is given by a real
vector $$x(t) in $$R^{N.}
Then an ODE for this system has the form:
This says that the velocity of the system (namely
$d$x/_{dt}) is a determined entirely by it's state (namely
$$x), via some function $V:$R^{N}
>R^{N}.


ODEs are ubiquitous in applied mathematics. For example:
 In physics: ODEs model trajectories in classical and relativistic
mechanics.
 In chemistry: ODEs describe the reaction kinetics of chemical systems.
 In biology: ODEs describe the evolving populations of
interacting species, fluctuating endocrine
levels in the body, or neural activity in the brain.
 In economics: ODEs describe business cycles.
Given an ODE, we can ask four questions:
 Do solutions exist? In other words, given an initial state $$x_{0},
is there a smooth curve $$x(t) satisfying $$x(0)=x_{0} and the ODE?
 Is this solution unique?
 What is an explicit formula describing the solution?
 What is the longterm qualitative behaviour of the system?

MATH 2260H[226H] 
Geometry I: Euclidean geometry
 Winter 2010 
Geometry is the oldest part of mathematics; its origins are lost
in antiquity. Classical Euclidean geometry applies logical deduction
to discover the relationships of lines, points, and circles in the
plane. For more than two thousand years, it has been the ideal of
clarity and elegance to which all other mathematics aspires.
In this course, we will cover some subset of the following topics:
 Constructions using compass & straightedge.
Nonconstructability.
 Triangles:
 Similarity & congruence.
 Ceva's theorem and corollaries.
 Symmetry:
 Isometries; Kleinian geometry.
 Symmetric planar figures.
 Friezes, tilings, and crystal structures.
 Symmetric polyhedra (Platonic & Archimedean).

Principia.

 Hyperbolic geometry.
 Toroidal geometry.
