An example of A Bird in Flight

A Bird in Flight are bird-like geometric patterns that were introduced by mathematical artist Hamid Naderi Yeganeh. Yeganeh has created these figures by combing through tens of thousands of computer-generated images. They are defined by trigonometric functions. An example of such patterns is a composed of 500 line segments where for each i = 1 , 2 , 3 , … , 500 {\displaystyle i=1,2,3,\ldots ,500} the endpoints of the i {\displaystyle i} -th line segment are:

( 3 2 ( sin ⁡ ( 2 π i 500 + π 3 ) ) 7 , 1 4 ( cos ⁡ ( 6 π i 500 ) ) 2 ) {\displaystyle \left({\frac {3}{2}}\left(\sin \left({\frac {2\pi i}{500}}+{\frac {\pi }{3}}\right)\right)^{7},\,{\frac {1}{4}}\left(\cos \left({\frac {6\pi i}{500}}\right)\right)^{2}\right)}

and

( 1 5 sin ⁡ ( 6 π i 500 + π 5 ) , − 2 3 ( sin ⁡ ( 2 π i 500 − π 3 ) ) 2 ) {\displaystyle \left({\frac {1}{5}}\sin \left({\frac {6\pi i}{500}}+{\frac {\pi }{5}}\right),\,{\frac {-2}{3}}\left(\sin \left({\frac {2\pi i}{500}}-{\frac {\pi }{3}}\right)\right)^{2}\right)} .
