Graph of a parametric equation that traces a four-leaf clover pattern. Each leaf consists of 3 lobes of increasing size, and a curved stem extends below the clover. Above the graph is the equation: y = -cos(t)cos(2t)/(1+√3t) x = -sin(t)cos(2t)/(1+√3t) for 0 < t < 19π/3.
Line drawing of a 3-leaf clover with some symmetric shading filling the outline. Above is the equation: r = (1-k²)(4 - 2sin(3θ) + cos(6θ) + 5(⌈(θ-π/2-π/40)/(2π) - 1/2⌉ - ⌈(θ-π/2+π/40)/(2π) - 1/2⌉)) for 0 < θ < 2π and 0 < k < 1.
