Unfortunately, I have never been lingering over such problem.
Probably you are right, so that some 'ad hoc' solutions, only for
certain classes of fuctions can be found.
I have been playing around with Mupad 4.0.2 yesterday and found that nice
feature. The function x/(x^2-4) is plotted within the 'notebook' (the
input / output area that includes both numerical and graphical results)
in the x range [-5,5] with ticks every half unit (only integer units
are labelled) and in the y range [-1.6,1.6], with ticks every 0.1.
Dotted lines at x=-2 and x=+2 are drawn.
If anybody would try to implement an algorithm for polynomial functions,
i could provide a comparison with the Mupad results.
