Student[MultivariateCalculus][DirectionalDerivativeTutor] - plot or animate the directional derivative

Calling Sequence

DirectionalDerivativeTutor()

DirectionalDerivativeTutor(f(x,y), [x,y]=[a,b], [c,d], x=xmin..xmax, y=ymin..ymax, z=zmin..zmax)

Parameters

f(x, y)

-

(optional) algebraic function in two variables

[x, y]

-

(optional) name of the variables

[a, b]

-

(optional) point at which the gradient is evaluated

[c, d]

-

(optional) direction Vector

xmin..xmax, ymin..ymax, zmin..zmax

-

(optional) ranges for plot

Description

• 

The DirectionalDerivativeTutor command launches a tutor interface that computes, plots, and animates the directional derivative of a function.

  

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

• 

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

• 

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

• 

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