Thanks for all your answers. I think there's a bug in my program because when I use the Tutor and put the direction of the limit, left or right, an error message appears "Invalid Direction".

I've tried with other functions, and the problem persists. I think it's a bug in Maple 18.

I have to say that my Windows is in Spanish, so the Maple Menu is also in Spanish.

@acer Thanks for your reply. I wanted the original plotting command. If I use the plot builder to plot a function I can get the code, else I can't.

Thanks for all your answers. I was asking for the original plotting command. I've noticed that if you use the PlotBuilder, you can manage to show the command, else not.

Thanks for both answers.
