Can One Equation Grow a Chrysanthemum?

BEHIND THE WORK

Can one equation grow a chrysanthemum?

One point follows the polar chrysanthemum curve. The first sine term makes the broad petal rhythm, while the fourth- and eighth-power sine terms cut smaller variations into the radius. Then x(t) = r(t) cos t and y(t) = r(t) sin t place that changing radius on screen for 0 ≤ t ≤ 21π. The result is one continuous planar trace whose petal sizes and folds keep changing instead of repeating one simple outline.

THE MATHEMATICAL RULE

r(t)=5[1+sin(11t/5)]r(t) = 5[1 + sin(11t/5)]−4sin4(17t/3) − 4 sin⁴(17t/3)⋅sin8[2cos(3t)−28t] · sin⁸[2 cos(3t) − 28t]x(t)=r(t)costx(t) = r(t) cos ty(t)=r(t)sinty(t) = r(t) sin t0≤t≤21π0 ≤ t ≤ 21π
