Math Credit Challenge

MrRubix · 11-8-2007, 01:23 PM

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.

www.google.com

but, um, seriously... for 100 credits? solve p = np.

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).

5+3=?

Find the area of the surface that is part of the sphere x^2 + y^2 + z^2 = 4z that lies inside the paraboloid z = x^2 + y^2.

If you want a challenge check out the one that destiny posted.

**MagicCarpetRide** · 11-8-2007, 03:55 PM

What is the square root of -1

**All_That_Chaz** · 11-8-2007, 04:05 PM

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

two trains leave chicago at different times going in different directions when do they meet up

**Shouka** · 11-8-2007, 04:47 PM

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

**Reach** · 11-8-2007, 05:35 PM

1 13 77 294 855 2071 ...

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.

If two people are having sex and a third one joins in, how many people are there?

Think carefully...

^_^

**pokelda** · 11-8-2007, 06:45 PM

thread sucks

silvercomet1525 · 11-8-2007, 08:36 PM

How about the Riemann Hypothesis?

...

Okay, is all seriousness... what is the next number in this sequence:

6, 35, 143, 323, 667, 1147, 1763, 2491, 3953, 5183...

Ten numbers should be enough to get rid of ambiguity of the sequence.

D:

It should proceed, after 2491...3599, 4757, 5767...etc.

You missed a value >_>...!
