Example 6.23. Show that , where C is the circle with positive orientation.
Explore Solution 6.23.
Enter the integrand and locate the singularities.
Find the singularity that lie inside C.
only singularity that lies inside .
The integrand f(z) is to be used is
Use Cauchy's Integral Formula to evaluate the integral of taken over C.
Thus, we have found the value of the contour integral.
