$\displaystyle \int_C \frac{z+i}{z^3 + 2z^2} dz$ , where C is the circle |z|=1 traversed once counterclockwise.

ok so the parameterisation of the contour gives $\displaystyle e^{\pi i t}, 0 \leq t \leq 2$

but i'm not sure how to continue becuase the $\displaystyle f(z)= \frac{z+i}{z^3+2z^2}$ is undefined at z=0 and at z=-2
