I believe they are primes

can u tell me why you took out the 1/(2^2) ?

EDIT: I should have added some comment to be clear; it's likely that tonio is right that the problem is misstated; nevertheless, if it is correctly stated then the above links are relevant. - Jul 25th 2010, 02:20 PMtonio

wait wait,

i think there may have been a mistake.

The 2nd problem is just simply:

1/(1^2) + 1(3^2) + 1/(5^2)

So it is simply the odd numbers. So would I just do 1/(3^2) * S= 1/9 * (Pi^2)/6 = (Pi^2)/ 54? Thanks - Jul 25th 2010, 02:26 PMundefined
In post #2, Soroban factored out (1/2)^2 because it evenly divides each term, and because doing so allows us to express the sum as a product of already known quantities.

For this problem, think about what happens when you add this series to the series that Soroban solved. - Jul 25th 2010, 02:33 PMsoyeahiknow
if I add this series to the one Soroban solves, it would just be back to the original series right?

OOOOO so all I have to do is ( original series - series with all the even numbers)= series for problem 2 ( the odd numbers). So (pi^2)/6-(pi^2)/24= (pi^2)/8

and what kind of problems are these called? Thanks so much and sorry for the typo in the beginning! I posted it at like 3 am. - Jul 25th 2010, 02:36 PMtonio
