Actually -- I lie. I did look at impdiff, but without some worked
examples for the implicit_derivative function, wasn't sure how to
proceed (it would be handy if everything was defined/described with at
least one or more worked examples -- a general comment, and not simply
one directed at Maxima). In looking at the basic description, it
involves an array function, amongst other things I'm not (as of yet)
familiar with. I was looking for the path of least resistance -- a
workable solution (that was somewhat more forgiving for newcomers than
this function seems to be) was posted earlier.
