Solve this math problem for the glory of Satan.

OpenStudy (compassionate):

\[\zeta(s)=\sum_{n=1}^{\infty}\frac{ 1 }{ n^5 }\]

OpenStudy (anonymous):

what the hell?

OpenStudy (experimentx):

OpenStudy (anonymous):

\[\large\zeta (5)=-\frac{16}{11}\sum_{n=1}^\infty\frac{\left( 1+2(-1)^n\right) H_n}{n^4}\]\[\large \text{Where}~H_n=\sum_{k=1}^n\frac{1}{k}\]See: http://mathworld.wolfram.com/RiemannZetaFunction.html http://gery.huvent.pagesperso-orange.fr/articlespdf/Autour_primitive.pdf

OpenStudy (compassionate):

>Everyone cheated.

OpenStudy (experimentx):

this isn't easy ... probably relies on Riemann hypothesis that hasn't been proven yet.

OpenStudy (compassionate):

No, try solving for all positive integers.

OpenStudy (experimentx):

I don't know ... and i would also like to know.

OpenStudy (experimentx):

according to the page i posted above ... it says it's unproved theorem.

OpenStudy (compassionate):

By analytic continuation, and thus, by analytic continuation, \[\zeta(-1)=\sum_{n=1}^{\infty}n = -1/2\]

OpenStudy (unklerhaukus):

oh ,

OpenStudy (compassionate):

Hail Satan for this math problem.

OpenStudy (experimentx):

try posting it here http://math.stackexchange.com/ I'm just starting complex analysis

OpenStudy (lgbasallote):

interesting....so many people willing to solve for the glory of satan...interesting

OpenStudy (anonymous):

lets not

OpenStudy (experimentx):

lemme ask people on chat.

OpenStudy (anonymous):

i'll ask @rezas for this problem but not for the glory of satan !!!

OpenStudy (experimentx):

those guys on MSE ... they say there isn't elementary expression for odd values of Riemann zeta function

OpenStudy (compassionate):

Everyone who attempts to solve this is doing it for the glory of Satan.

OpenStudy (anonymous):

i've evaluated \[\sum \frac{1}{n^3}\]with fourier series be4 i'll go for\[\sum \frac{1}{n^5}\]later..

OpenStudy (experimentx):

is that 2 or 3 ?

OpenStudy (experimentx):

i guess the problems is same for all $$1 \over n^{2k+1}$$

OpenStudy (experimentx):

I thought this kinda form would appear with Fourier series http://www.wolframalpha.com/input/?i=sum [1%2F%282n%2B1%29^3%2C+{n%2C+0%2C+Infinity}]

OpenStudy (experimentx):

\[ {1 \over (2n+1)^3}\] relies on zeta after all

OpenStudy (experimentx):

for now ... i give up :(((((
