Question: Right input, but unable to graph the space curve. Take a look, any setting changes?

^^^^^^^ that is from copying and pasting from the maple.

otherwise it'd look more like this

So... when i pressed enter it did nto do anything but retype the equation.

I need it to graph, I know this input is right because I looked at the teacher's example and it made a graph, but when I copy and pasted the teacher's example there were no graph. I believe this maybe mean that I need to do some setting changes maple, but where?

Please Wait...
