		AUTEUR(S): Ray Mah
Friezing at Washington State University
		This article is part of the Mathematics Notes series at Washington State University. In the article, Judi and Harley start by determining the functions that map the plane back onto itself, while at the same time, mapping a specified line back onto itself and preserving the size and shape of any objects represented in the plane. These are the functions that preserve frieze patterns. The authors then look at the algebraic structure of this collection of functions under the operation of composition, show that there are only seven frieze groups, and illustrate how they are generated. Each frieze group is represented algebraically and geometrically. The article concludes with a tour of the Washington State University campus, looking at the ways in which frieze groups are exhibited and used in our immediate surroundings.
		AUTEUR(S): Judith J. McDonald and J. Harley Weston
Further Properties Assigned to arcsine and arccosine
		Gregory and Oleksandr find more compact and efficient ways to express some identities involving arcsine and arccosine that appear in the Handbook of Mathematics. The expression Gregory and Oleksandr found was used to derive their arc midpoint computation.
		AUTEUR(S): Gregory V. Akulov and Oleksandr G. Akulov
Helen's Ride
		In this note Gregory uses his Arc Midpoint Computation formula to devise a problem regarding riding a bicycle around the University of Victoria campus.
		AUTEUR(S): Gregory V Akulov
Making the Connection: Patterns and Relations
		This one of the articles in the seventh edition of Ideas and Resources for Teachers of Mathematics, a newsletter published by the Saskatchewan Mathematics Teachers' Society. The theme of the seventh edition is patterning and algebra and in this article Alain shows how experiments can be used to make connections between formulas and real life situations.
		AUTEUR(S): Alain Gauthier
Math on the Farm
		This article discusses some of the many ways in which math is used in agriculture. It considers specific agriculture processes, as well as a variety of math concepts.
		AUTEUR(S): Natasha Glydon
On MY Mind (HTML ou PDF)
		In this note we consider a problem involving the ratio of two unknowns and contrast an algebraic solution with a graphic approach.
		AUTEUR(S): Diane Hanson
Pi Day Pie with Two..Foci
		Gregory gives a challenge problem with an elliptic pie.
		AUTEUR(S): Gregory Akulov
Puzzle Brings... Olympic Rings
		Gregory poses a challenge problem involving the Olympic Rings.
		AUTEUR(S): Gregory V. Akulov
Sciences Shine at LIT
		In this note Gregory creates a problem inspired by the Luther Invitational Tournament (LIT), a longstanding basketball tournament at Luther College High School in Regina.
		AUTEUR(S): Gregory Akulov
The Arc Midpoint Find
		Continuing his discussion of circular arc midpoint computation Oleksandr develops an expression for the midpoint of a circular arc in n dimensions.
		AUTEUR(S): Oleksandr G. Akulov
The art of Hamid Naderi Yeganeh
		Hamid Naderi Yeganeh is a student of mathematics at University of Qom in Iran. He likes to create beautiful images by basic mathematical concepts.
		AUTEUR(S): Hamid Naderi Yeganeh
The Map of the Land & Symbolic Extent
		Another challenge problem from Gregory, this time concerning the map of Saskatchewan.
		AUTEUR(S): Gregory Akulov
Why are satellite dishes parabolic? (HTML ou PDF)
		A development of the mathematics which shows that a parabolic shaped satellite dish will focus the signal from a satellite to the focus of the parabola.
