Plotting Guilloche Designs with Open Source Software

[myfullname]

Hello art Forum.
I am codifying some of the mathematical functions used in traditional Guilloche designs.
I have been relying on Inkscape's FunctionPlotter Extension for the simpler examples but am now up against Inkscape's limitations.
I need advice finding an open source application that can take multiple functions in typical one line format {sin(x*12/7)*((A-B)/2)+((A+B)/2)}, and output the plot as an svg file importable back to inkscape. I think asking here before I start to plod through the man pages of the 24 suggestions I got from another forum might save some duplicated effort.

Is Gnuplot appropriate for this? KmPlot? Any of the other endless "plot applications" that show up when I search?
I have watched too many bad youtube tutorials before bothering you here. I did try very hard to work this out on my own.
Advice is golden.

I have attached an image of two functions and the rosettes they generate.
Thank you for your time and thoughts on this puzzle.
Gratefully and with respect, Myfullname Jr.
