Sorry if this is too elementary.
I want to graph the derivative of a function y that is given implicitly as a function of x. I would appreciate any suggestions.
Unfortunately, this is pretty hard to do in Sage. Even this attempt (eventually) fails:
I don't know that this is easy to fix in general, either, because of course derivatives in implicit functions can be arbitrarily complicated to solve for, and so not necessarily accessible to a computer method. I don't think there are any numerical methods for doing this.

Surely there is a way to do this numerically, isn't there? What I mean is that one should be able to write a function which, for a given numerical value of
Of course this won't work for every implicitly defined function, but sage's numerics should work for a lot of cases that users actually want.
But I don't know enough about sage symbolics to actually do this. Any takers?
I am not sure whether this is what you are looking for
