Good graph plotting app [closed]
Does anyone know of a free graph plotting app for Windows (or an online tool) that can plot something like this?
Xn+1= r sin (π * Xn)
I'd like to suggest WolframAlpha, but it has trouble with the "r*". The best I could do is this.
I'd try Gnuplot or Octave/Matlab. If you had an Apple, the built-in Grapher would do the job.
See Science: Math: Software: Graphing for a few dozens of plotting applications.
