A Pythagoras-style Diophantine Equation and its Solution

By At Right Angles | Dec 14, 2018

The Pythagorean equation x^2 + y^2 = z^2 (to be solved over the positive integers N) is a much-studied one; many articles have appeared in this magazine alone, devoted to this equation. A close relative to this is the equation 1/x + 1/y = 1/z (which can be written as x^−1 + y^−1 = z^−1 ; in this form, its similarity to the Pythagorean equation is readily seen), and this too has been studied many times in At Right Angles.

Arsalan’s Amazing Area Problems

By At Right Angles | Dec 14, 2018

On the Facebook page (AtRiUM: At Right Angles, Us and Math) linked to this magazine, one of our contributors, Arsalan Wares, has been astonishingly prolific in posting problems. A good many of these have had to do with regular hexagons; more specifically, with the areas of polygonal regions drawn within such hexagons. It is both astonishing and pleasing to see such a rich diversity of problems arising from this simple and familiar structure.

Mathematics Olympiads in India

By At Right Angles | Dec 14, 2018

The history of Mathematical Olympiad (MO) activity in India is not available anywhere. Hence, while recording this history, we also mention the people who initiated and nurtured this activity. However, before we talk about it, we first highlight a few aspects of the International Mathematical Olympiad (IMO).

Adventures in PROBLEM SOLVING

By At Right Angles | Dec 14, 2018

In this edition of ‘Adventures’ we study a few miscellaneous problems, mostly from the Pre-Regional Mathematics Olympiad (PRMO; this year’s PRMO was conducted on August 19 in centres all over the country). As usual, we pose the problems first and present solutions later.

Pigeonhole Principle: Some Applications

By At Right Angles | Dec 14, 2018

The Pigeonhole Principle (PHP) or the Dirichlet Principle is perhaps the easiest theorem that exists in all of Mathematics. It states that if n + 1 pigeons are put into n pigeonholes, then there is at least one pigeonhole with more than one pigeon. The proof is as easy as the statement.
