[from the AwesomeMath Newsletter, The Gold Standard]
Just because the summer camp season is behind us for this year doesn’t mean you can’t still work with our AwesomeFaculty on interesting problems. AwesomeMath Year-Round gives students the chance to continue developing their insights and delve into important mathematical concepts and methods of proofs for problems and challenges that range to the Olympiad level. Our website describes the program as follows:
|Aug. – Sept. 2013||Titu Andreescu and Cosmin Pohoata||Gems in Euclidean Geometry|
|Oct. – Nov.||Titu Andreescu and Cosmin Pohoata||Harmonic Divisions Revisited|
|Dec. 2013 – Jan. 2014||Titu Andreescu and Adithya Ganesh||Gems in Algebra|
|Feb. – Mar.||Cosmin Pohoata||Topics in Combinatorial Geometry|
|Apr. – May||Titu Andreescu||Gems in Number Theory|
|June – July||Titu Andreescu and Adithya Ganesh||Sums and Products|
Register today for this unique opportunity to work with qualified instructors on Olympiad level math with individualized feedback.
Cosmin Pohoata will return to the Metroplex Math Circle this week to give a talk on symmedians. This will be an excellent lecture particularly for some of our more advanced students and those preparing for mathematical contests where symmedians can be a powerful part of their tool kits.
Abstract: We will introduce symmedians from scratch and prove the entire collection of interconnected results that characterize them. Applications from contests around the world will also be presented if time permits.
Constructions using only the compass and the unmarked ruler (straightedge) have always been something to be enjoyed by triangle geometers throughout time and to inspire many Olympiad problems nowadays. Here, we will see why this subject can be so appealing and will cover a few basic constructions for afterwards to challenge ourselves and see how these serve as natural “macros” for constructions which at first sight seem out of reach.
