Problem Statement

Let zz be a complex number with z=2014|z| = 2014. Let PP be the polygon in the complex plane whose vertices are zz and every ww such that 1z+w=1z+1w\tfrac{1}{z+w} = \tfrac{1}{z} + \tfrac{1}{w}. Then the area enclosed by PP can be written in the form n3,n\sqrt{3}, where nn is an integer. Find the remainder when nn is divided by 10001000.
