| − | My username is from the quadratic formula, which states that the roots of the equation <math>ax^2+bx+c=0</math> are

| − | ==Signature==

| − | Signature as of September 1st, 2011:

| − | <cmath>\sqrt{a+bi}=\sqrt{\frac{a+\sqrt{a^2+b^2}}{2}}+i\sqrt{\frac{-a+\sqrt{a^2+b^2}}{2}}</cmath>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 <math>a+bi</math> which can be derived from inputting that equation into itself.
| |
| − | ==Notable Work==
| |
| − | Discovered <math>\sqrt{a+bi}</math> in terms of <math>a</math> and <math>b</math>, 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).
