How to find removable singularity?
Step 1: Explaining how to find removable singularity:
A removable singularity of a function is a point where the function appears to be undefined. We can remove this singularity by redefining the function, then we can say we remove the singularity.
Step 2: Writing example:
at the function is undefined.
has a removable singularity.
Now the function has no singularity as we removed it.
Hence, in this way, we can find removable singularity.
