Topic: Polar coordinates

Is it possible to graph a half line, for example, t = 5pi/4 ?  Regards DFH

Re: Polar coordinates

No, you cannot do that. At least not with polar coordinates. It would require relations supporting polar coordinates, and I never got around to implement that. But you can of course do it as the standard function f(x)=tan(5pi/4)*x

Re: Polar coordinates

hallo, can graph plot a best FIT CURVE for  scatter plots

Re: Polar coordinates

Yes, you can use Function|Insert trendline to create a best fit for a point series.
