This is not unusual. Math SE receives a huge number of questions every day, and I would imagine that most of them receive only a small number of impressions. This is particularly true of questions which are posted outside of the most active hours (it looks to me like your question was posted very early in the American morning, which makes it less likely to be seen).
Moreover, my impression is that folk often skip over long questions which involve a lot of exposition or computation before getting to the point, particularly when they are of a "check my homework" flavor. The questions which typically get responses here (for better or worse) are those which can be quickly read and understood, even if the answers are more difficult to write.
In the future, if you feel that a question of yours is not getting enough attention, you might try the following:
Edit the question to narrow the focus or to draw attention to a key issue. I will hasten to add that you should not edit a question just to bump it to the top of the queue (editing a question makes it "active", which will promote it to the top of the "active questions" list on the front page)---such edits are considered somewhat abusive. However, if the question is not getting attention, it is very likely that it is because it needs some edits for clarity or concision.
Discuss the question in chat. The Mathematics Chatroom is probably a good place for drawing additional eyeballs to a question.
Put a bounty on the question.
In the future, please do not post meta questions asking why your main-site question is not getting any attention. If everyone asked these kinds of questions on meta, the meta site would quickly be overwhelmed with requests for extra attention.
