Your question is certainly better than a lot of the low-quality homework questions we get here, but at its core, what you're asking is "where do these formulas come from?" That's not a conceptual question. What we mean by asking about a specific physics concept is something like "What does the sin(theta) in this equation represent?" or "Is it valid to set w cos(theta) = 0 here?" (where you would present reasons why you think it might not be but you're not sure) or even "Why is this block able to slide up the incline when my calculations show that it shouldn't be able to?" Basically, you're supposed to dig down into your work and identify the one specific idea that you can't understand or figure out, which is keeping you from proceeding with the problem. A good rule of thumb is that you should be able to ask your one question in the title, and it shouldn't be "how do I derive this?"
So the bottom line is, no, you haven't showed enough effort. You're fairly close, though. With a little discussion here on meta we could probably help you figure out how to edit your question so that it would be on topic.
