**1. Homework Statement**

Locate & name the singularity of the function

Sinz /z- ∏

**2. Homework Equations**

**3. The Attempt at a Solution**

The function has singularity at z= ∏ but am not able to figure out what type of singularity it is , at z=∏ it gives 0/0 form which is indeterminate form , therefore it is not a pole , neither can the singularity be removed by approaching towards pi there fore it must be an essential singularity
