Or in other words:

1/(1^2) + 1/(2^2) + 1/(3^2) + 1/(4^2) +1/(...=

I tried using the same technique as last time by setting up the formula based on several values for n and then replacing any whole number values with an equation using n but this time the formula gets too complicated since the n value is in the denominator.

Any ideas?
