LOL, the mathematician want to go through a singularity. Why am I not 
surprised.

This was your question, huh? However, in a model (in applied Physics) one 
will always exclude singularities, just to get the related necessary info.

I would suggest you to rephrase your question, or to give detailed and 
required info for why it should be otherwise.

Listen up, that equation is invalid for x=zero. LOL.
