∫Cz+1z2−2zdz for the circle of lvertz rvert=3. Poles are obviously at z=0,2. Can I calculate the residues by viewing the fraction in the integral as either ∫Cz+1zz−2dz intC frac fracz+1z−2zdz and plug into 2 and 0 into those numerators respectively? That would yield a final answer of $ 2 \ pi i * (\ frac {3} {2} + \ frac {1} {- 2}) = \ pi i ps
¿Esto se ve bien? Soy nuevo en residuos y quiero asegurarme de estar en el camino correcto.
