    I think you would have got better answers or rather you will get more users to answer your question, if you would have posted the question alone, I mean try excluding the part "Hello all...........here goes the first"

    And you can also try posting the question with the equation in LaTeX format, in that way you can increase the probability too.

    And I think it must be dx instead of that x right?

    Ok now see this one "Evaluate the integral \[\int\frac{1}{(x^2\sqrt{x^2-16)}}dx\] using the substitution \[x=4\sec\theta\]" Is it OK?

    So I think I can summarize them as follows 1. Make it concise 2. Use equation editor 3. Use the chatrooms to attract users 4. Private message the people you think can solve the problem
