The GradientTutor command launches a tutor interface that computes, plots, and animates the gradient(s) of a function.

The values of f(a,b), f(c,d),.. and grad(f) at [a,b],[c,d],.. are calculated and displayed in the tutor interface.

If f(x,y) and [x,y]=[[a,b],[c,d],..] are not specified, GradientTutor uses defaults.

The Gradient command offers equivalent capabilities to GradientTutor where interaction takes place in the worksheet interface. See the Student[MultivariateCalculus][Gradient] help page.

To change the default colors of the plot objects, see the Student[SetColors] help page.

When the GradientTutor is running, interaction with the worksheet is not possible.
