Maple inserts the Student[MultivariateCalculus][GradientTutor]() calling
sequence (in Worksheet mode), and launches the Multivariate Calculus
Gradient Tutor.
By rotating the three-dimensional plot, you can show that the gradient points
in the direction of greatest increase of the surface (see Figure 4.12) and show
the direction of the gradient vector in the x-y plane (see Figure 4.13).
