<div align="center"><I>My question:
Find the functions f, g, u, and v such that:
c(p) = f(x)*g(h+p) + u(x)*v(w+p)

where h and w are defined by the definite integrals (D):
h(x) = D[0..x](f(x)dx)
w(x) = D[0..x](u(x)dx)

and c is a function of p, but a constant in x, i.e:
dc/dp != 0
dc/dx = 0

The functions f, g, u, and v each have the following properties:
* Continuous, real, and non-infinite.
* Non-zero, i.e. always positive or always negative.
* All functions are harmonic with the same period, a, i.e.:
f(x) = f(x+n*a), g(x) = g(x+n*a)
u(x) = u(x+n*a), v(x) = v(x+n*a)
where n is an integer.

Must see work, an answer only won't cut it.</I> - 29/7/2007</div>

This question fills me with that sinking feeling you get when you think you haven't studied enough.

Haven't got that far with calculus yet. Although, looking at the question, I'm only a few months study away from it... I'll come back to it. 8)


If all bodily functions, behavioral actions, moods, etc. come from the brain, which stimulated pattern causes people to up and kill another person? Figure out that one and you'd be a god.

why does sheetz have locks if they are open 24 hours a day 7 days a week?

why do you drive on a parkway but park on a driveway?

what color does a smurf turn if you strangle him?

Why is it that when someone tells you that there’s billions of stars in the universe, you believe them. But if they tell you there’s wet paint somewhere you have to touch it?

Did you ever notice that if you blow in a dogs face it goes mad, yet when you take him on a car ride he sticks his head straight out the window?

Why isn’t the number 11 pronounced onety one?


If man evolved from monkeys and apes, why do we still have monkeys and apes?


How do they get the deer to cross at that yellow road sign?

What was the best thing before sliced bread?


Do you realize how many holes there could be if people would just take the time to take the dirt out of them?

Why do kamikaze pilots wear helmets?

[spud yeti]

Why do they sterilize lethal injection needles?

[Pete Zaria]

Why do they sterilize lethal injection needles?

In case the condemned man is pardoned at the last minute. This has happened several times before.

Why do kamikaze pilots wear helmets?

Same reason; in case they were called back, the strike aborted, etc....


Somehow I have a feeling this thread is going to get retarded.

It hasnt already?

Then why haven't you simply locked it before things get out of hand?

I would imagine since light travels in quanta, which is packets of energy, and since energy in the form of light doesn't weigh anything, then mass cant increase because it has none. But thats just a stab in the dark.

EDIT: I thought mass increased by the mass dilation formula, not by an exponent...

Oh, I thought light had some (small)amount of mass to it.
I figured any non-zero-point energy had to have some type of mass.

Also, no, it doesn't increase by an exponent, but I was just phrasing the question to convey the general idea.
If I looked up/wrote out the formula I think my post would be ignored more because it includes numbers. Just as I haven't bother to read the jumble of variables on the first page.


Edit: Since I'm bored, I will attempt to answer spudthug's questions in a semi-smart ass fashion:

why does sheetz have locks if they are open 24 hours a day 7 days a week?

To keep out the angry mob that will gather when gas goes to $4/gal

why do you drive on a parkway but park on a driveway?

I'm not sure.
Maybe you should try parking in a parkway and report your findings.

what color does a smurf turn if you strangle him?

Blue, of course. You do remember that your tv is not adjusted properly, right?

Why is it that when someone tells you that there’s billions of stars in the universe, you believe them. But if they tell you there’s wet paint somewhere you have to touch it?

Because I really don't have time to count them myself.
It only takes a second to touch the paint.

Did you ever notice that if you blow in a dogs face it goes mad, yet when you take him on a car ride he sticks his head straight out the window?

Because your breath smells like ass.

Why isn’t the number 11 pronounced onety one?

You are perfectly welcome to pronounce it onety one if you want to.
I prefer "oneteen".

If man evolved from monkeys and apes, why do we still have monkeys and apes?

Because the apes decided they were happy the way they were, and did not feel the need to blow eachother up.

How do they get the deer to cross at that yellow road sign?

Where I come from, the deer that live near the signs are the only ones that survived.

What was the best thing before sliced bread?

Beer.

Do you realize how many holes there could be if people would just take the time to take the dirt out of them?

No.

(Again with the questions from me )

Because that would start a huge philosophic debate about punishing crimes before they are committed. Haven't you seen Minority Report?

[Modderxtrordanare]

Do you realize how many holes there could be if people would just take the time to take the dirt out of them?

What would we do with the dirt from the holes, if we dug up as many holes as possible? Conservation of Mass my friend..

Unless of course we launched it all into space, but then the world would be like a giant Louis Sachar novel.

[paaiyan]

SO I was talking with my chem professor once about the benefits of buclear power production. The only real drawback that either of us saw was the problem of disposing the waste. I asked him why they don't just launch it into space, he said it's apparently against the law. Does anyone know why it would be against the law to launch it into space? We could shoot the waste at the sun or something, it's not like we could blow it up or anything.

Whats 2+2x2?

2+(2*2) would be 6
(2+2)*2 would be 8

Actually, 2+2*2=8 and there is no ambiguity in the answer if you know all the rules.

Multiplication has higher precedence than addition.

Seconds guy's right, but this isn't science...
