Moved from a technical forum, so homework template missing.
Please can you help me with this question.
A surface h in the three dimensions is given by the equation z=g(x,y)
Find the unit normal at any point h in two separate ways:
a)By identifying h with an equipotential for some scalar field φ to be determined and computing ∇φ.
b)By expressing the points of h in parametric form r(x, y) and computing ∂r/dx × ∂r/dy
I think that you have to write h(x,y,z)=xi+yj+g(x,y)k
but can someone explain what a) means
thanks
