When I post a problem, I will enter the problem with numbers, and below it, show my work process. Then, they know where I've gotten and that at least I tried. You posted this problem carelessly, without numbers because of LaTeX, and does not include any of your work. Did I directly beg for answers from a certain person? No. If someone answers my problem I always thank them and read their explanations thoroughly, until I understand the problem. Then, I completely redo the problem trying not to look at their explanations, so I can grasp the meaning. Furthermore, you are directly asking for certain people to answer your problems. That's basically stating that one person is better than another. If you haven't noticed, I box my answers to make things neat and look better, not to feed people answers. I also give them an explanation, and if they don't read my explanations, I can't stop them. This ends here. That is final.
