Typesetting the commands



I'm using the texmacs front-end to maxima. When I enter a command, 
such as integrate( x, x); can texmacs be made to typset the command 
as well as the answer?

i.e. I'd like to see

/             2
| x dx = 1/2 x
/

(please forgive the terrible ASCII art)

Please cc me in your reply.
Many thanks,
Shaun
