Question

Express the residue of a function at an isolated singularity as a contour integral in​

Answer 1

Answer:

This Is Residue Theorem

Step-by-step explanation:

In complex analysis, a discipline within mathematics, the residue theorem, sometimes called Cauchy's residue theorem, is a powerful tool to evaluate line integrals of analytic functions over closed curves; it can often be used to compute real integrals and infinite series as well.

Answer 2

Answer:.:)

In the removable singularity case the residue is 0.) This says that the limit exists and equals the residue. Conversely, if the limit exists then either the pole is simple, or � is analytic at �0. In both cases the limit equals the residue.
