English: This figure is like a sailing boat. It shows 2,000 line segments. For each ${\displaystyle k=1,2,3,...,2000}$ the endpoints of the ${\displaystyle k}$-th line segment are:

${\displaystyle \left(\cos \left({\frac {6\pi k}{2000}}\right)-i\cos \left({\frac {12\pi k}{2000}}\right)\right)e^{\frac {3\pi i}{4}}}$

and

${\displaystyle \left(\sin \left(\left({\frac {4\pi k}{2000}}\right)+\left({\frac {\pi }{8}}\right)\right)+i\sin \left(\left({\frac {2\pi k}{2000}}\right)+\left({\frac {\pi }{3}}\right)\right)\right)e^{\frac {3\pi i}{4}}}$.
