Summary
| Description |
English: Mathematical "rose" or "rhodonea" curves, based on the polar-coordinates equation r=cos(θ*n/d). In this chart, the values of parameter n varies from 1 to 7, while d varies from 1 to 9. |

Own work This is an improved version of File:Rose-rhodonea-curve-7x9-chart.svg, which showed the analogous chart for r=sin(θ*n/d), but the period of each curve wasn't taken into account, leading to artefacts in the PNG thumbnail.
