comment Finding the limit at $a$ of $\left(\frac{f\left(x\right)} {f\left(a\right)}\right)^{\frac{1}{g\left(x\right)}}$
$\ln x $ is differentiable at $x\neq 0$ and $f(x) $ differentiable at $x$ so by the chain rule it's differentiable there? And this actually makes a lot of sense, though I'm not sure how I could think of something like that myself

comment One-one and continuous $\implies$ strictly monotonic
I think you mean contradicts injectivity, Edit: well you were faster than me :P

@tetori This is the next topic so I guess I'll realize it soon :P

comment Analysis: Basic Sequence Proof
Didn't downvote myself, but I think it's getting downvoted because it answers the half of what he asks that is "hidden" at the end.

comment Show that the series is absolutely convergent
Is showing that the series of absolute values converges enough to conclude that the original series converges absolutely, or do you have to show that the original series converges as well?

comment Does Russel's paradox preclude us from using the power set to generate every possible set?
Well as far as I understand, "the set of all things" is not a set, you can't just say "I take everything and call it $A$", and there is actually quite a delicate process describing what is or isn't a set.
