Examples on Singularities| Isolated Essential Singularity| Removable Singularity| Pole|Theta Classes

In this lecture we are given with 5 functions and we have to locate and classify the types of singularities. First we will have a brief discussion about Laurent's Theorem and then we will determine that our singularities is Essential singularity, Pole and Removable Singularity on the basis of principal part. After this we will be able locate and determine the types of singularities of given function.
