## How Do I rotate f(x) around the x-axis in MATlab or Mathematica?

Please help, I want a visualization of the function y = sech(x) revolved around the x-axis from x = -2 to 2, creating a "solid of revolution".

 Yes, but how would I use that in conjunction with the rotation? Could you give me an example please?
