Description: Illustration of Vogel's formula of the pattern of sunflower florets (see article) for n from 1 to 500, using the polar coordinates equations r=cn{\displaystyle r=c{\sqrt {n}}} and θ=n×2πϕ+1{\displaystyle \theta =n\times {\frac {2\pi }{\phi +1}}}. Can be produced using the following MATLAB code: n=1:500; r=sqrt(n); t=2*pi/((sqrt(5)+1)/2+1)*n; plot(r.*cos(t),-r.*sin(t),'o')
