### Re: Math Software

Does anyone know of a free program capable of graphing implicit functions in R 3 ? Preferably for Linux. I suspect someone does, yes. :roll: I've only tried gnuplot, and from what I can tell, it will only plot functions given in the form z=f(x,y). I want to plot surfaces given in the form F(x,y,z)=...

Draw the midpoint of A and B and a sphere with this midpoint as midpoint that goes through A and B. Then all tangents go through the intersection-circle of the two spher...
