What is wrong? I got erroneous results by plots.

 In: plot(sin(x))
 Out: Graph - incorrect!  

 In: plot(bessel_J(0, x), x, -0, 1)
 Out: Graph - incorrect!

I can send send you screenshots of both, but I don't how.

Post the images on imgur and add a link here.

Initially disguise the links by inserting spaces, as in

It might be helpful to know:

  • what operating system
  • how was Sage installed

Any reason not to install a more recent Sage?
