Complex Integrals - Poles of Integration Outside the Curve

[SirFibonacci]

Homework Statement

\int_{|z-2i|=2} = \frac{dz}{z^2-9}



2. The attempt at a solution

I know that the contour described by |z-2i|=2 is a circle with a center of (0,2) (on the complex plane) with a radius of 2. The singularities of the integral fall outside of the contour (z+3 and z-3). In this case, is the solution just going to be zero or undefined?

Your integrand is analytic in a region that contains your contour, what do you know about a closed contour integral of an analytic function?

The integral is 0. Makes sense. Thanks.
