Great. seems to work fine. The output is a bit weird though, in typeset sage, the diff(a(T),T) is written as D [ 0 ] ( a ) ( T ), not particular intuitive. But it works! Thank you.

jdpipe (Mar 23 '12) I'd like to know if there's a way of declaring functions in sage that are as-yet unknown. For example, let's say I have a function And I would like to be able to take a derivative like this and be given something back a partial derivative something like However at present I can't seem to put an abstract function As I recall there was a way to do this with wxMaxima, so maybe I just haven't found the trick in Sage yet. |

You can define a function using the keyword function. The script below gives the answer you expect. Great. seems to work fine.
