How does one define, given a complex function, the following:(adsbygoogle = window.adsbygoogle || []).push({});

- The function is analytic at infinity.
- The derivative of the function at infinity.

It turns out that it's supposed to be quite common to define these terms, however I have never been shown either of them. I have a few guesses, but along with some lecture notes I could put my hands on, it's all become a big mess for me.
