Figure 12.7 from page 158 of book Superfunctions^[1]:

Approximation of the shape of the sledge runner by ^[2] with the hundredth iteration of sin ^[3];

\( y=\sin^n(\pi/2)-\sin^n(x)\)

with single adjusting parameter \(n\!=\!100\). Super sin and the Abel sin functions, id est, SuSin and AuSin, can be used to evaluate the iteration of sin; then, the number \(n\) of iterate has no need to be integer.

This is improved version of image https://mizugadro.mydns.jp/t/index.php/File:Boyt.jpg the resolution of the image of the sledge is better, and the file is half shorter.
