x * x-1 = 1 because x-1 is just another way of saying 1/x, and: x * 1/x = x/x = 1
-1/ln(1-x) * 1/(1-X) or -1/((1-x)*ln(1-x))
∫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)

Cygnus x-1 was discovered by a team of scientists and rocket engineers at the White Sand Missile base in 1964.
cygnus x-1
The only "named" black hole is called "Cygnus X-1", for the first X-ray source in the constellation Cygnus.
The famously first-observed black hole in Cygnus known as Cygnus X-1 is about 6,070 light years distant.
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.
Cygnus is a constellation made up of many stars - it will not have a colour.

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).
Although predicted theoretically long before, credit for discovery of the first strong black hole candidate through astronomical observation in the x-ray binary system of Cygnus X-1 goes to Bolton, Murdin, and Webster in 1972.
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.
Which one - there are hundreds of stars in the Cygnus constellation
