\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?
