## rose curve
rhodonea
("rose") by the Italian mathematician Guido Grandi in the 1720s. It is given
by the polar equationr = a sin(nθ).
If n is odd the rose has n petals, if n is even
the rose has 2n petals, and if n = 2 the rose becomes
the quadrifolium. If n is an irrational
number, then there are an infinite number of petals. ## Related category• PLANE CURVES | |||||||
