This step includes identifying the domain and range of such functions and learning how to graph them. We also examine ways to relate the graphs of functions in three dimensions to graphs of more familiar planar functions.

Recall that the slopes due north and due west are the two partial derivatives. The slopes in other directions will be called the directional derivatives.

(This rounded “d” is usually called “partial,” so ∂f/∂x is spoken as the “partial of f with respect to x.”) This is the first hint that we are dealing with partial derivatives.

However, we have already seen that limits and continuity of multivariable functions have new issues and require new terminology and ideas to deal with them. This carries over into differentiation as well.
