Hello, i entered this in my SAGE and the result is an empty space, not the sphere i wanted:

x, y, z = var('x,y,z')
sage.plot.plot3d.implicit_plot3d.implicit_plot3d(x^2+y^2+z^2==4, (x,-3,3), (y,-3,3), (z,-3,3))

what more is necessary to have the sphere i want :-(?

Try removing "sage.plot.plot3d.implicit_plot3d." from your code

only: implicit_plot3d(x^2+y^2+z^2==4, (x,-3,3), (y,-3,3), (z,-3,3))

Indeed implicit_plot3d(x^2+y^2+z^2==4, (x,-3,3), (y,-3,3), (z,-3,3)) is sufficient and it does plot the sphere in Sage 9.1. Which version of Sage are you using and what is your OS?

hello! I am using sage 8.1, i open "SageMath 8.1 Notebook" and i got error with all the options you gave me :-( it is always a cell with no figure

the error that sage gave me in your codes is that it does not recognize the variables
