The partial derivative with respect to y is the derivative with respect to y where x is xed. 9.2. The short hand notation f x(x;y) = @ @x f(x;y) is convenient. When iterating derivatives, the notation is similar: we write for example f xy = @ @x @ @y f. The num-ber f x(x 0;y 0) gives the slope of the graph sliced at (x 0;y 0) in the x direction ...

The graph of z = f (2,y) is a snrfsce in three-dimensional space. The level curve f (z, y) = 7 lies down in the base plane. Above this level curve are all points at height 7 in the surface. The plane z = 7 cuts through the surface at those points. The level curves f (z, y) = c are drawn in the zy plane and labeled by c.

That is, we compute the derivative of f (x;y) as if x is the variable and all other variables are held constant. To facilitate the computation
