what is the sum of 1/n^2 from 0 to infinity?
I would like to know how tosolve that as well.
Isn't this the Euler Series?
Yeah, I think this sum doesn't converge, but I'm not sure. The ratio test and root test seem to be inconclusive in this case.
By integral test, it does converge
Oh right, this is the basel problem that Euler solved, which made him famous
Fair point, it does. Good catch siddharth!
ah sorry, i should have said 1 to infinity :-). 1/0^2 can obviously not converge
The answer is \[\pi ^{2}/6\]
