The discussion focuses on evaluating two complex integrals along a parabolic contour involving the logarithm of the conjugate variable, specifically ##\log\bar{z}##. The user expresses uncertainty about handling the logarithmic term and the argument of the conjugate variable, ##i\arg\bar{z}##. They consider using both line integral and parameterization approaches, specifically the contour parameterization ##(t, 1-t^2)##. A proposed solution involves transforming the integrals into forms suitable for numerical evaluation, with specific expressions for the radius and angle in terms of the parameter t. The conversation highlights the challenges of complex integration and the importance of proper parameterization for accurate results.

How to evaluate the following two complex integrals along a parabolic contour?
I need to evaluate the following two complex integrals along a parabolic contour, and I am not sure I know how to deal with the ##\log\bar{z}## in both cases. Since for the log term, I do not know how to find ##i\arg\bar{z}##. Also, if I used either the line integral approach vs parameterize the contour as ##(t, 1-t^2)##. Would I get the same answer?

##\int_{i}^{1}\ e^{(i\log\bar{z})} dz##

##\int_{i}^{1} \log\bar{z}dz## both on the contour ##y=1-x^2##

Thank you in advance

Say
z=r e^{i\theta}
The first integral would be
\int_0^1 dt e^{i \log r(t)}e^{\theta(t)}
where
r(t)=\sqrt{t^4-t^2+1}
\theta(t)=arctan\frac{1-t^2}{t}
Numerical evaluation seems applicable. The second integral would be
\int_0^1 dt (\log r (t)- i\theta(t))
 
@anuttarasammyak I just saw your reply. For some reasons, I did not get the notifications that you made a reply. Thank you so much for your solutions. I really appreciate it.
