    3. The attempt at a solution

    I don't see why the n is in the denominator

    reverse chain rule. What's the derivative of [itex]\frac{\sin(nx)}{n}?[/itex]

    If that doesn't make sense, then...

    you could use u-substitution to avoid going backwards.

    If you don't know u-substitution, that can be part of the problem.
