    define gradient(f.g) in terms of components of vectors f and g.

    how would we define gradient(f.g) in terms of components of vectors f and g
    (say i and j cap components): where both f and g are vectors

    What have you tried?

    Where are you stuck?

    At least show \vec{f}\cdot\vec{g}\,, and/or that you know how to take the gradient of a scalar.
