gleich vorweg, ich bin blutiger Anfänger und habe folgendes Problem.
Normal exportiere ich meine Abbildungen immer aus GeoGebra mittels TikZ und binde diese in mein Dokument ein.. Allerdings habe ich bei einer Grafik ein Problem:
Geogebra gibt mir den Rat ich soll Gnuplot verwenden, allerdings bin ich diesbezüglich etwas ratlos.
Hier mein Code, wie er von Geogebra ausgegeben wird:
\documentclass[10pt]{article}
\usepackage{pgf,tikz}
\usepackage{mathrsfs}
\usetikzlibrary{arrows}
\pagestyle{empty}
%<<<<<<<WARNING>>>>>>>
% PGF/Tikz doesn't support the following mathematical functions:
% cosh, acosh, sinh, asinh, tanh, atanh,
% x^r with r not integer
% Plotting will be done using GNUPLOT
% GNUPLOT must be installed and you must allow Latex to call external programs by
% Adding the following option to your compiler
% shell-escape OR enable-write18
% Example: pdflatex --shell-escape file.tex

Nur die Verbindungskurve aller Punkte (Spirale) gibt er leider nicht aus.
Über eure Hilfe freut sich,
Markus.
