Teaching MPPSC Assistant Professor Mock Test Series 2025 Engineering Mathematics Complex Variables Singularities
The nature of singularity of the function tan (1/z):
1
z = 0 is an isolated singularity
2
z = 0 is an isolated essential singularity
3
z = 0 is a non-isolated essential singularity
4
z = 0 is a removable singularity
