You're absolutely right about being about to evaluated the result (if
I understand you correctly). The beauty of Lisp is, you get a
symbolic result from 'differentiate', which you can either pass along
to another function, or apply it to the numerical values as you
mentioned. Though I would say it is done at a very low cost, rather
than 'free'. :)
