The residues of a complex function X (z) =at its poles area)1/2, and 1...
Concept:
Residue Theorem: If f(z) is analytic in a closed curve C except at a finite number of singular points within C, then
⁡f(z)dz = 2πi × [sum of residues at the singualr points with in C]
Formula to find residue:
1. If f(z) has a simple pole at z = a, then

2. If f(z) has a pole of order n at z = a, then

Calculation:
Given:

Poles are simple and located at z = 0, z = 1, and z = 2

At z = 0, the residue is:

At z = 1, the residue is:

At z = 2, the residue is:
