Find the asymptotes of a function

How can we find the asymtotes of a function? Especially curvilinear asymtotes.

You can take limits with Richardson extrapolation, for example.

But if you want to find an asymptotic form of a function, e.g. figure out that the function f(x) = x + exp(x), asymptotes to e^x for large x, then you probably have to do some symbolic analysis. The TaylorSeries package can help you find Taylor expansions around specific points.


Thank you very much indeed.
