Example 6.21. Show that , where C is the circle with positive orientation.
Explore Solution 6.21.
Enter the integrand and locate the singularities.
Find the singularity that lie inside .
The function f(z) in the numerator
Use Cauchy's Integral Formula to evaluate the integral of taken over C.
Thus, we have found the value of the contour integral.
