In mathematics, a rose is a sinusoid plotted in polar coordinates. Up to similarity, Mathematics, often abbreviated maths in Commonwealth English and math in American English, is the study of abstraction. ... In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. ... This article describes some of the common coordinate systems that appear in elementary mathematics. ... Several equivalence relations in mathematics are called similarity. ...

One obtains a rose-like graph with 2k petals if k is even and k petals if k is odd. Assuming you use the given form, the whole rose will appear inside a unit circle. Using sine instead of cosine, and vice versa, the graphs differ by a rotation of radians—or that , and the graphs coincide.

More interesting results arise when k is a rational. If k is irrational, without bounds on , a disc results. In more detail, if k is irrational, the number of petals is irrational, and the only thing preventing you from a solid-appearing disc is the upper limit on . Assuming a k of π, a limit of 2520 degrees (14π radians) will give you the first complete circle. A synonym for ball (in geometry or topology, and in any dimension) is disk (or disc Geometry In metric geometry, a ball is a set containing all points within a specified distance of a given point. ...
