Warum erscheinen diese Kurven, wenn bestimmte Koordinaten gr

I record polar coordinates as follows.
First I draw 1 point on radius 1 with a rotation of 2 pi. Then I draw a point on radius 2 with the rotation pi and then another point on radius 2 with the rotation 2pi. Then a point on radius 3 with rotation 2pi / 3, Mobdro then another point on radius 3 with 4pi / 3, then another point on radius 3 with 2pi etc. Lucky Patcher Basically I draw n points with radius n so that they are evenly distributed and a point lies on the 0 / 2pi angle. I get these strange parabolic-looking curves that open to the right. The more I graph, Kodi the more pronounced the curves look and the more curves appear. However, I can`t find an equation that the curves fit. I think i understand why they appear but i was wondering whether there is a way to predict exactly how they will look in more detail. Any help would be appreciated. Thanks!
