Reaper

I got 9th place in the longest game of Reaper, Game 18, and 16th in Game 19. I also managed to get a score of 2797 in Boxy, the temporary game that existed on October 4th.

negativebplusorminus

My username is from the quadratic formula, which states that the roots of the equation $ax^2+bx+c=0$ are \[x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\] which, when read aloud, is "negativebplusorminus..."

Signature

Signature as of September 1st, 2011:

\[\sqrt{a+bi}=\sqrt{\frac{a+\sqrt{a^2+b^2}}{2}}+i\sqrt{\frac{-a+\sqrt{a^2+b^2}}{2}}\]Pride goes before destruction, a haughty spirit before a fall. I swear on my honor that my work and my answers are my own; if I received help, credit is given.

Equation

I derived that equation myself, and I am quite proud of it. I have a similar one for the fourth roots of $a+bi$ which can be derived from inputting that equation into itself.

Notable Work

Discovered $\sqrt{a+bi}$ in terms of $a$ and $b$, without trigonometry (not even using DeMoivre's theorems), and is noted for using mostly correct punctuation, capitalization, and spelling in the Art of Problem Solving classes (see AoPS Online School for how this classroom operates).

Note that September 21 was one of the last days before AoPS changed the Wiki format.

Welcome to the AoPSWiki! The AoPSWiki is a wiki (or a publicly editable online resource) project administered by the Art of Problem Solving for supporting educational content useful to avid math students. Unlike most online resources, the AoPSWiki is meant to be easily readable by even the least advanced student. Also, the AoPSWiki, being a wiki, can be edited by anyone!

AoPSWiki runs on the MediaWiki software.

Getting Started

If you don't know much about how to edit a wiki, you might want to read the tutorial and the help files. You can also read what AoPSWiki is not.

Lastly, please read the policies of the AoPSWiki before editing, and why AoPSWiki is different from other online resources.

Also, here are some tasks you can do if you want to help out on the AoPSWiki:
