1. ## Evaluate the integral, complex integration, please help?

∫ Ln (2 + z) dz, Contour is the boundary of the square with vertices + -1 and + - iota

Show the details and evaluate, Cauchy's Integral theorem can be applied or not.

2. ## Re: Evaluate the integral, complex integration, please help?

Hey szak1592.

The first question is: Is the function analytic inside the boundary?

3. ## Re: Evaluate the integral, complex integration, please help?

I donno, you tell me
