    product rule ...

    \frac{d}{dx}[f(x) \cdot g(x)] = f(x) \cdot g'(x) + g(x) \cdot f'(x)

    chain rule ...

    \frac{d}{dx}(f[g(x)]) = f'[g(x)] \cdot g'(x)


    ... and derivative rule ???

    1. Consult your textbook.

    2. Consult your class notes.

    3. Google was created for questions like this.

    4. There are hundreds of questions posted at MHF that use these rules (all to be found in the Calculus subforum, by the way. Not Pre-calculus) - and MHF has a Search tool.

    If you have a particular question that you need help with, post it - together with your attempt at answering it and a clear statement of where you get stuck.
