Image: Lissajous curve 5by4

Description: A Lissajous curve, that can be expressed in parametric form as: x = A sin ⁡ ( a t + δ ) , y = B sin ⁡ ( b t ) {\displaystyle x=A\sin(at+\delta ),\quad y=B\sin(bt)} with a = 5 {\displaystyle a=5} , b = 4 {\displaystyle b=4} and δ = π / 2 {\displaystyle \delta =\pi /2} . I created it with the following GNUplot code: set samples 5000 set terminal svg set output "Lissajous_curve_5by4.svg" # plotting within a square set size square # remove most of information from the picture set noxtic set noytic set key off # plot set parametric a=5 b=4 delta=pi/2 plot [0:2*pi] sin(a*t + delta),sin(b*t) with lines linewidth 2 and then I post-processed with Inkscape
