I read it in a context which implies that it is

i retract the question

Are simple functions complex-analytic?

@bolbteppa, i am about to go and i will look at your videos. but in your opinion this integral will be straightforward?
Jan 25, 2015 02:28
@bolbteppa thanks. i will check it out
Jan 25, 2015 02:05
@bolbteppa, When you say diagonalize do you mean take a change of variables? Or do you mean just re-express this exponential? I'm afraid my calculus background is a bit weak, not very familiar with integrating forms
Jan 25, 2015 01:53
even if I get it in that form, I'm not sure how it will work
Jan 25, 2015 01:53
interesting, @bolbteppa. Do you think he is right that this will help me solve the integral?

Does anyone understand this terse answer: math.stackexchange.com/a/1118201/28480

Would someone be kind of enough to read my own proposed solution to my question here: math.stackexchange.com/questions/1098220/… ?
Jan 5, 2015 18:44
ok, thanks @Hippalectryon

My answer was downvoted here: math.stackexchange.com/questions/1089188/… . Can someone explain it?
Jan 5, 2015 18:31
@MikeMiller it is most likely someone here because the question had no activity or comments for a day until a minute after i posted here
Jan 5, 2015 18:27
i ask for an evalutation of my answer in chat and then just get a downvote with no explanation. frustrating!
Jan 5, 2015 18:16
someone downvoted my answer. can i get an explanation?

Would someone kindly look at my attempted answer to this question: math.stackexchange.com/questions/1089188/…

@khalil, f is just some function of epsilon and t
Dec 10, 2014 15:28
Suppose I know that $|a-b|>t$. Can this lead to an inequality of the form $|a-b|>f(t,\epsilon)?$

Intuitively the above shows that $TA\approx TB$ and multiplying by $T^{-1}$ we have that $A\approx B$...
Dec 2, 2014 01:36
If $T$ is an invertible matrix, and for matrices $B$ and $C$, and we have that $\|TA-TB\|<\epsilon$, can we say that $A$ and $B$ are close to each other in some sense?

anyone here know about unbiased estimators?

but it's a little far out there, and Jung was basically a cult leader. but there was something fascinating about it. though i imagine in practice it's usually quite banal
Oct 8, 2014 07:36
i was once interested in the idea of Jungian psychotherapy

do you have a special diet?
Oct 8, 2014 07:34
@JasperLoy what's wrong with you?
Oct 7, 2014 12:34
not the problem i posted
Oct 7, 2014 12:34
what problem are you referring to? i have no idea what you're talking about
Oct 7, 2014 12:33
@N3buchadnezzar what is g?
Oct 7, 2014 12:26
@N3buchadnezzar i figured it out
Oct 7, 2014 12:21
@N3buchadnezzar did you understand it?
Oct 7, 2014 11:58
@N3buchadnezzar how is your calculus? mine should be decent, but for some reason i can't understand an answer of whuber's using integration by parts
Oct 7, 2014 11:54
hey @N3buchadnezzar
Oct 7, 2014 11:34
not seeing how he gets the (1-F(x))
Oct 7, 2014 11:34
should be a basic question...
Oct 7, 2014 11:34
can someone help me understand the second integration by parts component of this answer: math.stackexchange.com/questions/959988/…
Oct 6, 2014 15:57
any probability theory people here? math.stackexchange.com/questions/959988/…
Oct 6, 2014 14:45
any folks here know decision theory, or probability?
Oct 6, 2014 12:04
i hope so, @Nick
Oct 6, 2014 11:44
it shouldn't be this hard!
Oct 6, 2014 11:43
i don't know if it's up your alley, @Nick, but for some reason this problem is really stumping me and i would really appreciate it if someone could give me a clue what i'm missing
Oct 6, 2014 11:42
yes, @Nick
Oct 6, 2014 11:40
@JasperLoy @Nick?
Oct 6, 2014 11:40

anyone here?
Oct 6, 2014 14:43
just curious, you are the only guy here :) and i am desperate
Oct 6, 2014 14:38
I am stuck on a problem that should be easy: math.stackexchange.com/questions/959988/…
Oct 6, 2014 14:37
@GavinSimpson, do you know any decision theory?
Oct 6, 2014 12:04
@GavinSimpson, are you here?
