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.
