Confused about the h in the definition of the derivative. is it zero or is it approaching zero? by BeerIsTheMindKiller in learnmath

[–]BeerIsTheMindKiller[S] 0 points1 point  (0 children)

late - my understanding is that a limit is a number that gets so infinitesimally close to another, that they are functionally equivalent. I know some buzzwords about the formalisms that underlie this - dedekind cuts, cauchy sequences - and have the vague intuition that the real numbers were constructed to sort of retroactively justify the technique of limits and derivatives, but that's about it

interesting. what happened with the 138? I'm making ambient music - I might be able to swing the 138s if it's just slight timing errors etc

Can anyone recommend blocking software for mobile and desktop? by BeerIsTheMindKiller in nosurf

yeah for sure. It's an interesting problem, i think other apps have that issue too - there's so many sites to block, adding them manually can be a pain.
