I have asked Extremals of functional $J = \int_{a}^{b} F(x, y, y^{'})$ question on December 21st 2013..
Now comes another question An MCQ for finding the extremal of the functional $J = \int_{a}^{b} F(x, y, y^{'})$ which was asked in May 22 2015.
My question has been closed as duplicate by marked as duplicate by Normal Human, Harish Chandra Rajpoot, Claude Leibovici, N. F. Taussig, Deutsch Mathematiker yesterday citing that "This question has been asked before and already has an answer. If those answers do not fully address your question, please edit this question to explain how it is different or ask a new question."
It is clear that my question is older. Some user has said that "I picked this as duplicate because the other was older, and had some personal effort show there, which is not there here!" But then even without cross verifying, above mentioned users closed my question as duplicate.
This is not good. I protest this kind of practice. I want that duplicate tag to be out of my question..
