Question: Plotting 2d space curve

Hi I am reading this help document

and I cannot get maple to plot the same exact graph on that page, I receive this error

It only lets me plot 3 dimensional curves

When I downloaded the help document, the command executed. I cannot get it to work on my worksheet.

I even tried adding with(Student[VectorCalculus] ): and that did not help. 

I am clueless why this is not working.

Is there a way to upload a maple worksheet so you can see the error.

Please Wait...
