If you can not follow, it is just a serious reason for you to be in trouble.


It means, at least, that you are in wrong class (gently saying . . . )



Also, please keep in your mind, that this forum's goal is not to provide answers to you.

Its goal is to teach students to solve problems --- assuming that they want and able to learn.



In the future, if you allow one more such comment, I will write to your MANAGERS / professors / professor, 
asking them what you are doing in this forum.



From year to year I provide hundreds and thousands first class solutions for visitors at this forum,

and I will not tolerate boorish comments.
