Mathematical calculation in Inkscape
Hi,
I have the following code. I shows two half eclipses and one half disk. They represent 3 functions. I want to draw the function f1(x)+f2(x)+f3(x). Is there any exact way to do it in svg?
Thanks, Peng

Hi Peng Yu,

You hold down the shift key while you mark f1(x), f2(x) and f3(x). Then Path > Union. That's very simple - but perhaps you didn't mean this?

No, I didn't mean this.
Say f1(x)=sqrt(1-x^2), f2(x)=sqrt(1-(x-1)^2), f3(x)=sqrt(1-(x-2)^2), I want to plot f(x)=f1(x)+f2(x)+f3(x)=sqrt(1-x^2)+sqrt(1-(x-1)^2)+sqrt(1-(x-2)^2).
Thanks, Peng

Not sure if that is possible - or even a good idea for Inkscape - but for starters you should look at "Effects, Render, Function Plotter".
"Right tool for the right job". I would strongly recommend you take a look at gnuplot or any mathematics or plotting software. When you have generated your complex plots you could then export as SVG or EPS depending on what your software allows and finish off your work in Inkscape.
The author of the Function Plotter effect clearly wants to expand this extension even futher and include many more features (so many that he wants to group them into seperate tabs, which was recently discussed on the developer mailing list). You might want to try and contact him and maybe try out newer versions of Inkscape for testing.

Alan,
Have you seen or used the new version of function plotter with tabs?
