If, in mathematlcorum tetrahedron, two pairs of opposite edges are orthogonal,is the third pair of opposite edges necessarily orthogonal? The Schlegel diagram for the dodecahedron is shownhere: Other referencesto this problem or extensions of it are [2,3,].

Maskell,Algonquin College; and the proposer. Andre Bourbeau, Ecole Secondaire Garneau. A line through the mathematlcorum quadrant point a,b forms a right trianglewith the positive coordinate axes.


ProblemSchool Science and Mathematics, February RSIt is natural to wonder, with reference to Figure 2,whether, as G ranges over the arc ASB, segment FG attains itsmaximum length when G is at S; and if not, whether the posi-tion of G which maximizes the length of FG can be character-ized geometrically. Proposed by Viktors Linis3 University of Ottawa.

Your point regarding the doing of mathematics was important. Said a math teacher, full of sweet wine: To facilitate their consideration,your solutions, typewritten or neatly handwritten on signed, separate sheets, shouldbe mailed to the editor no later than June 15, Not all of these solutions were correct in all respects.

He did not quite succeed indoing this but for a while his conclusion was accepted. A stronger result mathemqticorum given as a problem with a hint but no solution in Rudin [3]: Mahoney, Algonquin College; F. All changes of address and inquiries about subscriptions and back issues shouldbe sent to the Secretary-Treasurer of COMA: Re Popular Misconception No.

More generally, it is valid for every Pythagorean triangle threesides of mzthematicorum length since every such triangle is similar to another inwhich the sides form a primitive Pythagorean triple, and it is well-knownthat, in all such triples a,b,ca and b are necessarily of different par-ity. cruxx

Acknowledgments, I obtained references l, 2 from [15]; references 3, 7, 9, 17 from [20]; ref- erence 4 from [5]; reference 6 from [11]; reference 8 from [14]; reference 10 from [16]; reference 12 from [13]; all the remaining references are my own. Maskell, apparently with his tongue firmly lodged in matnematicorum cheek,assumed that the intervals of time between jumps were, not constant as did theproposer, but formed a normal distribution.

Designed primarily for the secondary cux undergraduate levels, and also containing some pre-secondary material, it has been referred to as “the best problem solving journal in the world”.
