Derivative of (sin x)(cos x) divided by √x.?

Question

I can't figure out how to do this problem, so an explanation and some work shown would help greatly. Thanks.

My calculator can find the answer, but I really need help with the "how-to" part...

Answer 1

It is simple if you separate (sin x)(cos x) divided by √x into

((sin x) divided by √x)   * (cos x)

Then use Product rule for the two separated terms

Then use Quotient rule for ((sin x) divided by √x)
