SUMMARY
The integral of the function dz/(2+z*) over the closed curve C, where C is defined by z=1, can be evaluated using Cauchy's integral formula. The key to solving this integral lies in expressing z* in terms of z, particularly when z is on the unit circle. By utilizing polar coordinates, one can derive an analytic expression for z* that is valid within this context, facilitating the evaluation of the integral.
