    Derivative of a Trig Function

    Hey guys, could you please explain how to solve this, step by step? Hopefully it's fairly easy but I just can't get it:

    f(x) = xe^xcscx

    Find f'(x)

    Thanks!

    \frac{d}{dx}[u(x) \cdot v(x) \cdot w(x)] = u'(x) \cdot v(x) \cdot w(x) + u(x) \cdot v'(x) \cdot w(x) + u(x) \cdot v(x) \cdot w'(x)

    The way you wrote it could mean many functions. Can you verify which equation you are using (use parentheses or use Latex coding)?

    1(e^xcscx) + ((e^xcscx)(cscx - xcscxcotx))X
