How are $x \gg 1$ and $x \ll 1$ defined in your field or problem? I believe translating that to the language of Series[] or Asymptotic[] is the key to the choice of the point for expansion. In terms of asymptotic expansions, Wikipedia is typically opaque, but for "the point x=0," take in the Wikipedia article $L = x_0$ and for finite $x_0$, $\varphi_n(x) = (x-x_0)^n$ 'in the limit $x \rightarrow x_0$'; and in the limit $x_0\rightarrow\infty$, $\varphi_n(x)=x^{-n}$.

| Jun 2, 2021 at 14:38 | comment | added | Michael E2 | People here generally like users to post code as Mathematica code instead of just images or TeX, so they can copy-paste it. It makes it convenient for them and more likely you will get someone to help you. You may find the meta Q&A, How to copy code from Mathematica so it looks good on this site, helpful | |
