    So what exactly is your problem here? I can think of two ways to do this. Parametrize the curve or use the complex antiderivative. Both are easy. Do something!

    ok,i try to solve for integrate z dz= x+iy(dx+idy) and get dy dx from y=2x.and i get the answer for integrate z dz,
    how about the answer for integrate complex conjugate of z? since complex conjugate of z is not analytical .can i do it in the same way oso?
