Integral(2*y/(x^2 + y^2) + 1, (x, 0, 1))
Integrate term-by-term:
The integral of a constant times a function is the constant times the integral of the function:
The integral of is .
So, the result is:
The integral of a constant is the constant times the variable of integration:
The result is:
Add the constant of integration:
The answer is:

1 + I*log(-I*y) + I*log(1 + I*y) - I*log(I*y) - I*log(1 - I*y)
=
1 + I*log(-I*y) + I*log(1 + I*y) - I*log(I*y) - I*log(1 - I*y)
