off topic slightly, but it works!
OK, here's mine:

c2 = a2 + b2 -+ 2*sqrt(a2b2- 4K2)

Where a, b, and c are the sides of a triangle, and K is the area of said triangle.

You can get it two different ways:
1. Multiply out Heron's Formula and go crazy reducing it
2. Flip the Law of Sines around and plug it into a flipped Law of Cosines.

PM me for the proof.
