Wait, if you evaluate *within* the radius of convergence, does that work?

Convergence
edit

Unlike an ordinary series, the formal power series is not required to converge: in fact, the generating function is not actually regarded as a function, and the "variable" remains an indeterminate. [EGGMAN]: What are you two FUCKING talking about?

Okay I may regret asking this but: What the fuck are generating functions. I know they are good for like Putnam stuff but what, where do they come from, lol.

Because he's one of the only people standing next to a Republican going, "this person is a piece of shit, I don't respect him, neither should you, he's fucking evil and he needs to go, and I don't care if it makes me sound rude saying it" LIKE EVERY DEMOCRAT SHOULD BE DOING??? MAYBE???

Ok and does any of this have to do with, once again, 2.3 million lines of Lean code produced by glorified autocorrect

I'm not even sure Liberty Biberty is failing. The Insurance Wars exist because insurance is the least marketable industry. You can't really try out different brands to compare, it doesn't work visually on TV. The only way to sell it is to be as loud and annoying as possible so people remember you
