    Finding the convergence of the infinite series

    Consider the series: SUM (when k=1 to k=infinity) of 1/(k^2). I know the series converges to some value S, but how can I find out what S is?

    I'll look that over, but is there an easier way to do it?

    There is no easy way. We use tests just to know if series converge or diverge. The only series we can compute easily would be like geometric series or Maclaurin series or perhaps telescoping series...

    ... if I knew of an "easier" way, I'd have posted it myself.

    Well if I am told the 100th partial sum is approx: 1.635, is there a way (that is easier) to show that the convergence value is within thousandths of that number?
