1 / | | x + 1 | ----- dx | x - 1 | / 0
Integral((x + 1)/(x - 1), (x, 0, 1))
There are multiple ways to do this integral.
Rewrite the integrand:
Integrate term-by-term:
The integral of a constant is the constant times the variable of integration:
The integral of a constant times a function is the constant times the integral of the function:
Let .
Then let and substitute :
The integral of is .
Now substitute back in:
So, the result is:
The result is:

The answer is:
/ | | x + 1 | ----- dx = C + x + 2*log(-1 + x) | x - 1 | /
-oo - 2*pi*I
=
-oo - 2*pi*I
-oo - 2*pi*i
