COMPLEX ANALYSIS - Question of the day 10/04/2019, Q.1, Q.02,Q.03,Q.04 AND Q.05
Residue/pole/Singularities problem
important point:
*order of pole
*Singularities-Isolated singularities, Removable singularities,
*   Non-Isolated singularities and essential Singularities
*Objective question of pole
*Objective question of Singularities and residue
