@jksuom the latest commit is responsible for deprecating `calculate_series` function from `gruntz.py` . I haven't really dealt with deprecations before so would be glad if you could have a look...

The failing test in **test / optional-dependencies (3.11.0-alpha - 3.11, true) (pull_request)** don't seem to be because of the code changes I've made today .

I also found that #6350 was pending because sympy lacked `_eval_nseries` implementation for `besseli` function . So currently we have the following on master ``` >>> k = Symbol('k') >>>...

A last thing we could try getting through this Pr , is something that was pointed out on the gitter channel. > The nseries of (1 + 1/x)**k could be...

> This is a small change, though I'm not fully sure if there is something more, I need to take care of while handling these cases i.e., n = -k...

Hello @Parcly-Taxel , would you help me fix the failing test here . It came into picture because #23985 was merged some days back. The Pr involved changes in `_eval_rewrite_as_tractable`...

Using the rewrite function as tractable functions which we have currently might not always work . ``` def _eval_rewrite_as_tractable(self, n, m=1, limitvar=None, **kwargs): if not isinstance(pg, harmonic): return pg.rewrite("tractable", deep=True)...

Okay I realize there is a small problem with how the code flow is executed . What's wrong with the general code is the following ``` >>> x, y =...

Thanks for the extensive reviews on this one @jksuom @oscarbenjamin !!

Hello @oscarbenjamin , not really related to the issue here but as I see good amount of rewrites being enabled for trig/hyperbolic functions I thought of asking my doubt here...
