I posted a question on Phys.SE and the question was closed as off-topic. As a matter of fact I did a mistake when selecting the tags, since I used the homework tag. When I realized that I did a mistake I modified the tag, however the question was closed as off-topic. I really would get an answer to my question, so have I to post the question once more ? Why it wasn't enough to modify the tags?
Your question appears to fit within the definition of homework-like used on the site, the tag should be applied and the question (in its current state) should be closed.
If you look at the question I've just linked you to and at the one linked in the close message, you may find some guidance for render your question into a form suitable for the site.
Given the sophistication of the work you exhibit I would be unsurprised if you were able to retool to a question we'd accept.
