Integral((x^2 - 2*x + y^2)/(x^2 + y^2)^2, (y, 0, 1))
There are multiple ways to do this integral.
Rewrite the integrand:
Integrate term-by-term:
The integral of a constant times a function is the constant times the integral of the function:
Don't know the steps in finding this integral.
But the integral is
So, the result is:
The integral of is .
The result is:
