take it "Tan(a) is just a constant?

i`d suggest converting the sin(x) cos(x) to (1/2)Sin(2x), the cos^2(x) to (1/2)(1+cos(2x))

Yes, product rule and chain rule; remember that tan(a) is a constant...

You do not need to convert SinxCosx and Cos^2x to anything (unless you've been asked to present your answer in a specific form). It just complicates the problem. Differentiate the function directly.
