Dear Proofathoners,

We are just days away from the Proofathon Spring Competition. This competition will cover the areas of Algebra, Number Theory, Geometry, and Combinatorics. The prizes are as follows, the upper places receiving all of the prizes of the lower places as well:

1st gets his/her name added to the Proofathon Super Hall of Fame. 3rd gets a copy of Mathematica, as well as a Proofathon t-shirt. 10th gets a commemorative score certificate. Everyone gets the experience in solving maths problems.

I wish you luck, I will see you at proofathon.org this Friday, the 28th at 0:00 EST. The contest is one week long, so that should give you ample time to compete and succeed.

Good luck, Proofathoners!

Prove that for all real \(x, y,\) and \(z\),

\[ |\cos (x)| + |\cos (y)| + |\cos (z)| + |\cos(y+z)| + |\cos(z+x)| + |\cos(x+y)| + 3|\cos(x+y+z)| \geq 3.\] – Calvin Lin Staff · 3 years, 4 months ago
