Contour integration using residue theorem (quick question)

Click For Summary
SUMMARY

The discussion focuses on contour integration using the residue theorem, specifically addressing a homework question regarding poles and residues. The participant identifies poles at z=-1 (order 3), z=1, and z=2, confirming that since there are no poles within the specified contour, the residue is indeed zero. This conclusion is validated by another participant, emphasizing the correctness of the reasoning applied in the context of complex analysis.

PREREQUISITES
  • Understanding of complex analysis concepts, specifically contour integration.
  • Familiarity with the residue theorem and its application in evaluating integrals.
  • Knowledge of poles and their orders in complex functions.
  • Experience with mathematical notation and terminology used in advanced calculus.
NEXT STEPS
  • Study the residue theorem in detail, focusing on its applications in complex integration.
  • Learn about different types of poles and their contributions to residues.
  • Explore examples of contour integrals with multiple poles using complex analysis techniques.
  • Investigate the implications of residues in evaluating real integrals through contour integration.
USEFUL FOR

Students and professionals in mathematics, particularly those studying complex analysis, as well as educators looking for clear examples of applying the residue theorem in contour integration problems.

The Attempt at a Solution


So i have poles at: z=-1 of order 3, z=1 and z=2. For part i), no poles are located inside the contour, therefore the residue is 0. <--is that right to say, that since there are no poles inside the contour, the residue is zero?
