\label {PID} and \ref {PID}
At 04:33 in the video, it is being said that the concept of "\label{PID}" and "\ref{PID}" has already been discussed in the tutorial no. 05. , but actually it is not discussed. I have gone through the entire tutorial no. 05, but their no mention of PID anywhere.

1) Can you please explain in detail some more information about PID ?

2) What if I want to refer to 2 different equations at 2 different places in the text of my document. How should I use the PID for doing this?

PID is just a variable.  What the video says is that the concept of "label" is already explained.

You can use anything else also in the place of PID.  For example, you can say something like \label{eqn1} and \ref{eqn1} or \label{eq:1} and \ref{eq:1}.  What is important is that the variable used in \label should be referred to exactly in \ref.
