Help required on how to do the following:
to evaluate : integral (z+i)/(z+2i) dz where curve is semicircle from 0 to 4i, initial point 0
and where curve is circle |z-2i|=2 anticlockwise.
what is the radius of the semicircle from 0 to 4i ?
In the case where the curve C is given by |z - 2i| = 2, the integral is 0, since (z + i)/(z + 2i)
This provides an example of integration using Cauchy.
