Richard Rusczyk (/ ˈ r ʌ s ɪ k /; Polish: [ˈrustʂɨk]; born September 21, 1971) is the founder and chief executive officer of Art of Problem Solving Inc. (as well as the website, which serves as a mathematics forum and place to hold online classes) and a co-author of the Art of Problem Solving textbooks.
For years, the idea of extending the training program for the U.S. IMO team was discussed. During the 2004–2005 school year, U.S. IMO team coach Zuming Feng directed the Winter Olympiad Training Program, utilizing the Art of Problem Solving (AoPS) site for discussion purposes. The program was short-lived, lasting only that year.
The American Invitational Mathematics Examination (AIME) is a selective and prestigious 15-question 3-hour test given since 1983 to those who rank in the top 5% on the AMC 12 high school mathematics examination (formerly known as the AHSME), and starting in 2010, those who rank in the top 2.5% on the AMC 10. Two different versions of the test ...
The AMC 8 is a 25 multiple-choice question, 40-minute competition designed for middle schoolers. [4] No problems require the use of a calculator, and their use has been banned since 2008. Since 2022, the competition has been held in January. The AMC 8 is a standalone competition; students cannot qualify for the AIME via their AMC 8 score alone.
The AMC10 only participants will take part in USA Junior Mathematical Olympiad. [10] 1.Selection to the USAMO and JMO will be based on the USAMO index which is defined as AMC score + 10 * AIME score. 2.Only AMC 12A or AMC 12B takers are eligible for the USAMO (with the slight exception mentioned in item 5 below).
Replace some a i by a variable x in the formulas, and obtain an equation for which a i is a solution. Using Vieta's formulas, show that this implies the existence of a smaller solution, hence a contradiction. Example. Problem #6 at IMO 1988: Let a and b be positive integers such that ab + 1 divides a 2 + b 2. Prove that a 2 + b 2 / ab + 1 ...
The Baltic Way mathematical contest has been organized annually since 1990, usually in early November, to commemorate the Baltic Way demonstration of 1989. Unlike most international mathematical competitions, Baltic Way is a true team contest.
The number of points (n), chords (c) and regions (r G) for first 6 terms of Moser's circle problem. In geometry, the problem of dividing a circle into areas by means of an inscribed polygon with n sides in such a way as to maximise the number of areas created by the edges and diagonals, sometimes called Moser's circle problem (named after Leo Moser), has a solution by an inductive method.
