I wish there was a way to tell whether the start in the sky still exist. Some of these stars are millions of light years away. DOnt you think that some of them would be dead by now and we are just waiting to see them dissapear?

-2 = -2
1-3 = 4-6
1^2 - 2(3/2) = 2 ^2 - 2(3/2)*2
adding (3/2)^2 to both lines
(1-3/2)^2 = (2 - 3/2)^2
cancelling squares and eliminating commons
1 = 2
similarly 2 = 3,
3 = 4,
4 = 5,
5 = 6 ...
explain giving as much details as not possible.

1. The length of a picture without its border is twice its width. If the border is 2cm wide and border's area is 208 square cm. what are the dimensions of the picture alone?

2. The perimeter of a rectangle is 20 meters. If the length is increased by 2 meters and the width is increased by 3 meters, the area is increased by 30 square meters. What is the length of the rectangle?

In many cases, in America, if a man marries a woman from another country (& vice versa), that woman becomes a citizen of the USA. How would this apply to an alien (ET)?

Hi. I'm trying to find a Fourier series for:

(sin(x))^2

It seems like it should be pretty easy but I'm having trouble getting the An term.

I've converted the (sin(x))^2 into terms of cos(2x), which seems like it should do something, but I'm not sure what. The integral still seems tough. Any help would be appreciated.

Thanks.

will only taking sun's pictures show us that science is growing up?
i think this is waste of time and waste of funds and resources. Our planet doest have any danger from Sun. lets move too far to discover and achieve better things in space rather than sticking around the sun. I think this probe is fruitless.



Why on our earth the sounds on the sun, which are the result of reactions taking place on it, can be heard? hopefull these sounds and explosions could be heard from near by planet mercury or venus!
