Proofathon Spring Competition

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!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

An example of a past Proofathon problem:

Prove that for all real $x, y,$ and $z$ ,

$|\cos (x)| + |\cos (y)| + |\cos (z)| + |\cos(y+z)| + |\cos(z+x)| + |\cos(x+y)| + 3|\cos(x+y+z)| \geq 3.$
