Functions

Absolute Values

Select an argument (Arguments, -3z - +3z)

describe it,  generate it, and click the Display the Sequence command. Select (Functions, Absolute Values) and change the names of the argument and its absolute values function to z and |z|.

Stereoimages

To plot the function, select Stereoimages

and click the Image Data on Vector Display command.

Select |z| and click the Accept command.

Select Colors and change color of Background to the brown color and color of Axis Foreground, Axis Background and Labels to the white color. Select (Settings, Axis), remove the check mark from the Use Dim Name command, erase Names of the X- and Z-axis and click on the OK command.

Graphs

Select Graphs

and click the Cube Graphs command. Select the Abscissa and the Ordinate

to view the function of the absolute values |z| for the z argument.

Stereographs

Select (Stereographs, Display Stereograph)

to view the graph of the absolute values in the black and white,

or select (Stereographs, Define Stereograph)

to view the graph of the absolute values in the graded colors.

Linear Functions

Select (Data, Univariate Prototypes) to enter variable X [1 2 3 4 5]. Click in the Variable name and change X to Miles. Open scalar module and select the (Transfer, Vector -Scalars) command. Select (Information, Measurement Units, Distances). Drag the first scalar value to the Distance input box and click the Miles to Kilometers command. At this point your screen should look as

Drag the remaining values from scalar display to the Distance input box and from the Miles to Kilometers output box back to the scalar display. Send the converted distances back to vector module by clicking the (Transfers, Scalars - Vector) commands. This works for small data sets. In the case of large data sets, clear the scalar display (Clear Scalar Display) and click on the bottom Miles to Kilometers command. The scalar display should look as

Select (Functions, Linear Functions) commands, drag the B value from the scalar display to the Slope input box, enter 0 as the Intercept.

 and click on the Append command. Rename the new variable on the vector display Kilometers and click the (Graphs, Line Graphs) commands. Check the Miles and Kilometers variables, click on the Accept command,

and the graph of the linear function  y = .621x  will be displayed on the computer screen.

Sinusoids

To visualize a sine function, select (Arguments, Cyclic Sequences) fill-in the required fields, and click Display the Sequence

Next, select (Functions, Trigonometric Functions, Sine), and click the Accept command.

 

Select Stereographs, mark the X and Y coordinates, and click on the Display Stereograph command.

You can also use color, by electing the Define Stereograph instead of the Display Stereograph command,

and define colors,

to obtain the sine function in the color of your choice.
