==Equations for the Roots of the Complex==
 
<cmath>\sqrt{a+bi}=\sqrt{\frac{a+\sqrt{a^2+b^2}}{2}}+i\sqrt{\frac{-a+\sqrt{a^2+b^2}}{2}}</cmath>
 
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.  I have also found various roots of unity in their radical forms during my spare time.

A AoPS member, National MathCounts qualifier, and USAJMO qualifier.

Contest Results

MathCounts

In 2011, as a 7th grader, I didn't qualified for the State Countdown Round. In 2012, as an 8th grader, I lost the National MathCounts.

In the National competition, and scores as the worst.

AMCs

2012: 17 on AMC 10A, 27.5 on AMC 10B, 1 on AIME, 37.5 index for USAJMO. The cutoff was a 999.5, so I did not qualify for the USAJMO. However, I got 0 on the USAJMO. That thing is hard.
