How do I implement this module of hyperbolic geometry commands?

I am new to Sage. I'm trying to get around some very tedious hyperbolic geometry computations. I'm okay with defining functions and writing very basic things. I found this page indicating commands to compute a whole bunch of amazing things that I'd love to be able to use: http://doc.sagemath.org/html/en/refer...

But if I type the commands listed, Sage does not recognize them. For example, if I try to do what they say to do on that page and type

HyperbolicPlane().UHP().get_geodesic(2,3)

I get an error message that 'HyperbolicPlane' is note defined. How do I implement whatever that person did to get Sage to do all those awesome things?

Hmm! What version of Sage are you using, and where (e.g. cloud, notebook, CLI)? I get your error in Sage 6.5 but it seems to be fine in 6.8.

I confirm it works for me on Sage 6.8. As @kcrisman suggested, you should provide more details.

@kcrisman That is encouraging there might be a solution. I'm trying to figure out what version I have and how to upgrade it. I'm also new to using Linux and that's what I'm running Sage from.. trying to learn more though.

Okay, turns out I have 5.8. Now I'm working on how to update it.

I'm running Linux Mint 32, and having trouble finding a version of Sage for that. Any ideas?
