Question

Please answer 5.3 and 5.4

Let f(z):
=
e2z+3
22-z-6
26 and let C be the positively oriented contour C = {z € C : |z − 1| = 5}.
(5.1) Find and classify the isolated singular points of f and calculate the residues at these points.
(5.2) Use Cauchy's residue theorem to calculate fo f(z) dz.
(5.3) Why is it not possible to apply Cauchy's integral formula to calculate fo f(z) dz, directly?
(5.4) Calculate fc f(z) dz, by appropriately splitting fc f(z) dz into two integrals and applying
Cauchy's integral formula to each of these (it needs to be clear from your solution that you
are using Cauchy's integral formula and not Cauchy's residue theorem).
