thanks for not helping anyways, this assignment is done with...

don't mind the index... its there, because it sets the infinity on top of the SUM OF: and sets the n=1 down below it... any clues... there not homework... extra credit

This one too please 4) Derive the following, for 0 < or equal x < or equal 2(pi) infinity Sum of: cos(nx)/n^2 = (3(x)^2-6(pi)(x)+2(pi)^2) / 12 n=1

I really need someone to answer this by tomorrow 12/01 10:50 am pacific time... 1) Derive the following, for any integer k. infinity SUM OF: 1/(n^(2k)) = ((2(pi))^(2k)(-1)^(k+1)B2k ) /(2(2k)!) n=1 where Bn is defined by the following, for |x| < 2(pi). ````````````infinity (x)/(e^(x)-1)...
