Graphics, Figures & Tables ⇒ cube root functions

[coachbennett1981]

Good evening, below is the code I have for generating a cube root of x function, but when I plot it, the pdf file won't generate. It says

GPL Ghostscript 8.70: Unrecoverable error, exit code 1
### FAILED to generate /tmp/altpdflatex.94297-1286246774/Section 1.6 Transformations of Functions.pdf ()

What did I do wrong?

Code: Select all

\documentclass[10pt]{article}
\usepackage{pstricks-add}
\pagestyle{empty}
\begin{document}
\psset{xunit=1.0cm,yunit=1.0cm,algebraic=true,dotstyle=o,dotsize=3pt 0,linewidth=0.8pt,arrowsize=3pt 2,arrowinset=0.25}
\begin{pspicture*}(-5,-4.46)(5,6.3)
\psaxes[labelFontSize=\scriptstyle,xAxis=true,yAxis=true,Dx=1,Dy=1,ticksize=-2pt 0,subticks=2]{->}(0,0)(-5,-4.46)(5,6.3)
\psplot[plotpoints=200]{-5.0}{5.0}{cbrt(x)}
\rput[bl](-4.2,-1.9){$f$}
\end{pspicture*}
\end{document}

only God knows what cbrt should be, but not GhostScript ...

However, it looks like that you create your code with a gui,
the reason why you always have a lot of unneeded definitions.

cbrt=cube root. I used Geogebra to do the sketch because I could not figure out the code. That was the code expressed from the the function.. Thank you for your help.

then file a bug report to geogebra
