Summary
edit| Description |
Alternate version of interlaced five-fold "quinquetra" pattern. This version made from curves based on the quasi-Limaçon/Rose polar coordinates equation r=b+sin(aθ), with parameters b=1.4 and a=5/4 (see File:Mathematical-polar-equation-flowers.svg ). For versions of the quinquetra made from circular arcs, see File:Quinquetra-pattern.svg and File:Pentacle-knot-15crossings.svg . |
