Math Credit Challenge

[MrRubix]

Ask me any math question (that can actually be solved), and if I get it right, you owe me 100 credits. If I get it wrong, I'll give you 200 credits.

lol, brb.

What's the sum of the function f(n,a) = 1/(n^2+a^2) over all n in element of the natural numbers and for any a in element of the complex numbers.

No using math programs.

This is part of my favorite math problem.

Or you could do my favorite problem.

Starting with the geometric series prove that the above sum from 1 -> infinity for a = 0 is equal to pi^2/6 (this doesn't require complex analysis, just creative thinking).

you may as well have said what's 5+3, except the answer to yours can be typed more quickly

Darn, I used to know how to do that one foilman. I could probably try to dig up my calc 3 notes, but I'm too lazy

A formula exists which will allow you to determine the sum of the first N terms of the infinite series above. What is the formula and what is the sum of the first 10 terms?

I can make harder ones if you desire >__>

good luck trying to use Calc III to find that out.
