sorry didn;t had time to write it correctly but I think that the result is correct  notice that cosa=cos(a)   ans sinna=sin(na)  but I had not time to wrote it .....

if D is bounded by y=px^3,y=qx^3,y^2=ax,y^2=bx,where  o<p<q  and  0<a<b

I just get a very problematic integral to solve at the end .
I made the substitution  y/(x^3)=u  p<=u<=q    and    y^2/x=v    a<=v<=b  but I can't get the result......

Solve by substituing in polar coordinates this integral 

  if D={(x,y): sqrt(x)+sqrt(y)=1,x=>0,y=>0}

Sorry,I had no tine to see if latex scaned it well,but thanks a lot for helping me Bobbym.

The result are taken from a russian book of mathematical analyse(a very old book I can say) and I wanted to try to log the expression but as I said I hade no time to think so much,and I don;t understand russian,I just can read it but not understand it(if it would be serbian I could maybe understand a little),so thank you very much for helping me bobbym and Soroban.

Another diplomatic victory of the new born state of Kosovo.

In the controversy challenge between Kosovo and Serbia,Kosovo beats Serbia by 10:4 where the president of ICJ says: "the 17th february declaration of independence of Kosovo doesn't break any general international law...,the declaration of independence is conform international law and 1244 UN resolution.....,the delcaration of independence was legal"

It's time to say again and very loud "Bye bye serbia,bac u kry krejt qitash tongue"

Here are the things I wrote before,in an better english.I just found it while searching something else.

Just search science projects in it

E is the elctric field,the very elementary piece of the surface that you inegrate,pesilon mean the electric features of the meidum where is the area and q is the electrical load

if you have density you have to make

and to continue.

Do you want to make a specifi case ?
For sphere or cilinder with density??

#15 Re: Help Me ! » physics formula, dont understand the maths » 2010-04-17 08:28:54

it is

E is the electric field,which is inependent in this case so

if you ahve just one elecric load it is just q

If you have a sfear,the area is



#16 Re: Help Me ! » contour integral notation » 2010-04-17 08:17:00

It is an integral,an integral wich is resoklved as an normal integral,as I know.
It is used to integral circular surfaces.
It is like the Gauss law in electrostatic

#17 Re: Dark Discussions at Cafe Infinity » Purpose of life???? » 2010-04-11 01:45:52

Well, as it is written in the Quran,the last prophet was Mohamed..

But,I know some thing about the Dejjal..

The Dejjal is a one eye blind persone,wich will say that he is God,because he will have "supernatural" forces and will rule the world...I know that a lot of fals personne will say that they are the Dejjal...I know that there is a secret society who is eccpecting his arrival,and their sygns is the "everything sight eye" or how it's called in english.....
I know that he will rule the world,and when he will came to Mekka,Jesus will descend from heaven into the Mosuqe,and when he will open the door,the Dejjal will be so scared and he will run away,and Jesus will kill him with an arrow....

I think is't like the Antichrist,even if I didn't read so much about it..........
I saw a book of Nostradamus about the 3 world war and I made a copy of it a week ago,but I must go and take it at the library.....
I read just shortly an islamic book about prediction of the 3WW and it was quite interesting...
It's a bit complicated because I have to explain events which will take place and I read that book last year so I don;t remember,but I just know that the 3WW will be between the coallision USA-Muslims-EU VS Persia(Iran)-Russia-China if I remmber well ........
It's like I think like the Armagedon

#20 Re: Dark Discussions at Cafe Infinity » Purpose of life???? » 2010-04-10 08:07:51

It is hard to explain it by writting but I will try.

The Quran first of all describes also how to live...

How to arrange proble between couples,and other thing..It like a life guide,that's why everything is based on the Quran
The Quran raise people with high qualities and punish bad attitude and bad action of people,like killing,having intercouse with soemeone exept your husband/wife
The Quran has specified ways how to give punishment to someone,not just saying that he/she is guilty,but you must have 3 testimonials who ahve seen the act,excpt some act like killing and hidding the body,and other things because there are not always 3 persone,but specifies how to act in those case...
For example,if you steel something,they cut your hand,to be a punishment to you,so you can not steel any more,otherwise you will lose your hand and to be a good lesson that steeling is not a quality of a muslim.....that's way there are no so many case of steeling in some islamic states.....

Another example,I heard on tv that in afganistan a new law was approved,the law that let hsuband make intercouse with their wives even when they do not want to,by force!!!!
I am againts that law...thing's like this are not from the islamic law,because the islamic law respect everyone's right and do not make differences between people for some purposes,does not raise men from woman,but every one have their duty and responsability and their rights...
In the Quran,Allah recalls to those poeple who judge people from their desire from His punishment in the other world.....
In one word,if the islamic law would pe applicated how it really must be,there would'nt be any fals punishment,because some people have used the islamic law to amke terror among his people,like in Egypt by Naser as I know and other places,like Iran today..
Iran should change his name,Islamic Republic of Iran pfffffffffffffffffffffffffffffffffffffffff Iran is far being an islamic country......

There are scholars who study the Quran,the islamic law

I can not tell exactly what is right and what not,because I don't know everything from the Quran,but I judge from the way that I must be correct to everyone and to have facts before saying something to someone because there is a proverb  "the spoken word is like an arrow,you msut be carefull before releaisng it,becus it can not be back"
That's why lies and calumny are punished in Islam,they can make people suffer even if the have not done anything bad.....
The Quran is a book for everything.....So I don't like when I see on tv people saying "I kill in the name of Allah",that;s not true......
I'm quite sure that thing wich appears on tv about islam are things wich were prepared by some people to make a bad image of islam,because islam specifiec everyone act  in their life and does not support thiefs and those kind of people....

It is hard to explain,maybe you can find more information from someone in you city who knows better the islamic law,but you can see the real islam by reading the Quran than from magazines and tv....
If it would be so,I would thing that Catholocism is full of pedophiles,and it is not!!!!!!!!!!!!!!!!!!!!!
There are bad people in every sides,so for understanding each other we must learn from each other

#21 Re: Dark Discussions at Cafe Infinity » Purpose of life???? » 2010-04-10 06:57:21

for example in afganistan......there are people who interprate in such a extremiste way some things in the Coran,wich really aren;t....and the force the others to do it....for example the womans,the may have a terrible life under the taliban regime,but God has raised the position of woman in the Coran...but these people interpret it like they want to....I don't like this kind of people...I prefere Saudi Arabia wich in some ways practice "almost" everything right from the Coran....there are so many extremist who say that they kill in the name of God!!!!! I hate those poeple because God wants from use to respect each other,not to kill each other and a lot of other things....

#22 Re: Dark Discussions at Cafe Infinity » Purpose of life???? » 2010-04-10 05:29:31

Yeah the Coran is Unique,so you have to be carefull from who you take knwoloeadg about it...there are people who use it fore good purposes and others for bad purposes....

#23 Re: Dark Discussions at Cafe Infinity » Purpose of life???? » 2010-04-10 05:27:53

Of course,Islam respect alls,but  the most important thing to be a muslim is to believe in God and to amke prayers,beign a muslim is being a normal human wich rworship He's God as He wanted so...there is nothinge to be surprised....we are all humans

#24 Re: Dark Discussions at Cafe Infinity » Purpose of life???? » 2010-04-10 05:25:52

No I didnt't,I just wanted to discuss the point of view of everyone about the purpose of life...
Even if I want,I can not make you belive all....
This is not my purpose......
Lie you are giving you opninion about some things I also express my opninion and then I give some fragments from the Quran..
The word "heaven" do not sertainly mean "gameboy",the word is veru clear...and I don't care what do you believ or not..I respect you decision and this is all

#25 Re: Dark Discussions at Cafe Infinity » Purpose of life???? » 2010-04-10 05:20:58

What kind of preven??
The Coran isn't an ordinary book!!!!
Why so Nostradamus didn't predict something about science but just events?????

I can write some things that the Coran has predicted,but I don't know if we will be alive to see them.........
THE Coran is more than a predictable book of events,at all who cares about what Nostradamus predicted,they are small events,and I do not match thing that aren't true.

As I see,you din't read carefullt what I've wrote in some other post.....You can ask some one who knows better the Coran than I for things that you are interested...And YESSSSS a good question from you....Search about someone who can give more information about events in the future,because my speciality isn't the Coran,my speciality are maths and physics,and you will see that you will get information that you never event croosed you mind about islam

The Coran predicts the end of the wrold in some places in it.......How it will come and wich are the signs.....
Here:our prophet Mohammed(peace be upon him) said that one sign for aproaching the end of the world(this is a small sign because there are small and big signs) are bulding skycraper but with he's words,because this word din't exist,the growing of prostitution,the great number of singers... and the big signs are something else......

The most important of big sign will be when the sun will rise in the other side as go ask someone who knows the Quran and speaks english better than I and he/she will expalin more carefully details...It doesn;t cost you anything to try or to search in internet about scientific facts in the Coran

My knowleadge abut the Coran is like a single  drop of water in the ocean........
