On the other hand Dmitrii's plot of the derivatives looks quite like yours:

where is red; is green; is blue; is pink.

Compared with Jays suggestion, which has a completely different second derivation:

[attachment=3]

So can it just be a rounding error (Taylor series)?

And why not ask Dmitrii, to compute for to infinity, whether it wobbles or not

Dmitrii, can you do this?
