I am a new learner of Mathematica, I input
Plot[Sin[x],{x,-4,4}]
after enter, no image was shown, only got the result
Out[4]=-Graphics-
, no graphs was shown, I tried many times, but why failed? What wrong with that? How should I do? Should I install any extra software of Mathematica?
Use the graphical interface, not the command line version.
On Linux, start mathematica, not math.
Thank you Mr. Horvat for your response. I am learning Mathematica by that which is built in raspberrypi(Because I do not have the Window version of Mathematica), also I am a new learner of raspberrypi. So I do not know how to enter into the graphical interface. Can you give me more guidance?
By the introduction of you online, I realize how intelligent you are and how significant the research you have done/is doing about human brain.
Thanks you again!

I already fixed my problem by creating notebook file(.nb), then press “shift+enter”, the graph at once existed.
