What does x times x to the power of negative 1 equal?
x * x-1 = 1 because x-1 is just another way of saying 1/x, and: x * 1/x = x/x = 1
What is the derivative of lnln1-x?
-1/ln(1-x) * 1/(1-X) or -1/((1-x)*ln(1-x))
What is the integral of 1 over 1 minus x squared?
∫1/(1-x)2dxWe can rewrite the integral as ∫(1-x)-2dx.Thus:∫(1-x)-2dxu = 1-xdu = -1-1∫-1(1-x)-2dx-1∫u-2du(u-1|0u=1-x(1-x)-1So we conclude that ∫1/(1-x)2dx = (1-x)-1 or 1/(1-x)
Log x plus 7 equals 1 plus Log x-1?
logx +7=1+log(x-1) 6=log(x-1)-logx 6=log[(x-1)/x] 10^6=(x-1)/x 1,000,000x=x-1 999,999x=-1 x=-1/999,999
What is the integration of 1 divided by x3 plus x?

What is the nearest blackhole to earth?
cygnus x-1
Who discovered Cygnus X-1?
Cygnus X-1 was discovered in 1964 by astronomers Tom Bolton and Chuck Gulkis at the University of Toronto. They identified it as a strong X-ray source in the constellation Cygnus, using data from the U.S. Aerobee suborbital rocket.
How are black holes named?
The only "named" black hole is called "Cygnus X-1", for the first X-ray source in the constellation Cygnus.
How many light years is the black hole cygnus?
The famously first-observed black hole in Cygnus known as Cygnus X-1 is about 6,070 light years distant.
Who identified Cygnus X-1 as the first black hole?
Cygnus X-1 was identified as the first black hole by astronomers Tom Bolton and Louise Webster in 1971. They observed the star in the Cygnus constellation exhibiting characteristics consistent with a binary star system with a massive unseen companion, leading to the identification of Cygnus X-1 as a black hole.
What is Cygnus X-1?
Cygnus X-1, as far as we know, is a black hole; it therefore does not have a size. However, as with all black holes, it does have an event horizon and this radius is estimated to be around 26km.
What is the color of the cygnus?
Cygnus is a constellation made up of many stars - it will not have a colour.
Which was the first black hole candidate to be discovered?
The first black hole candidate to be discovered is Cygnus X-1, which was identified in 1964. It is located in the constellation Cygnus and is one of the most studied black hole candidates due to its strong X-ray emissions.
What color is the color of Cygnar's Cygnus emblem?
Gold and blue -JM
What constellation is home to the first known black hole?
It is believed that there is a black hole in the constellation of Cygnus (the Swan), the strong X ray source Cygnus X-1 is believed to be a binary system where one component is a black hole. (see the link Below).There is also a super-massive black hole in the center of our galaxy (the Milky Way) this is to be found in the constellation of Sagittarius and is called Sagittarius A*. (see the link below).
What makes Cygnus X-1 a good black-hole candidate?
Cygnus x-1, which is found within the Swan Cygnus constellation, is a binary star system and one of the brightest sources of x-rays in the sky. Data collected from this system indicates that there is a compact "object" that is 9 solar masses. As well, its brightness has been observed to be continually changing, which is a characteristic of a blackhole, and simply cannot be otherwise explained.
What is the color cygni?
Which one - there are hundreds of stars in the Cygnus constellation
