    3. The attempt at a solution

    I'm not sure how to go about integrating this, i.e. integration by parts, substitution etc?

    Any ideas?

    Hint: I would probably make it a little easier by making the sub y = wt first to get a simple argument for the cosine. Then sub y = 2x and apply the double angle formula for cosine and simplify the integrand.
